Dental implants have become increasingly popular among general practitioners (GPs), largely due to advancements in technology that have significantly improved osseointegration and long-term success rates. However, despite these technological improvements, implant failure rates have paradoxically risen over the past decade, often due to improper planning and execution during placement.
The primary challenge in this case involved achieving the correct bucco-lingual angulation during implant placement. Improper angulation can lead to an over-contoured lingual aspect of the crown, which necessitates the thinning of porcelain to correct occlusal discrepancies. This not only compromises the aesthetic outcome but also increases the risk of porcelain fracture and long-term implant failure. Additionally, ensuring proper implant placement in relation to the crestal bone level was critical to allow for an optimally functioning and aesthetically pleasing cement-retained crown.
To address these challenges, a buccal rotation of the implant was strategically planned and executed. This adjustment ensured that the final crown would have a more natural contour, reducing the need for excessive porcelain thinning. Moreover, the implant was positioned at an equi-crestal level to facilitate the use of a cement-retained crown, which provides better aesthetics and ease of maintenance compared to screw-retained crowns.
The treatment concluded with satisfactory results, both functionally and aesthetically. The patient benefited from a well-integrated implant with a crown that exhibited proper contour and occlusion, minimizing the risk of future complications. The strategic buccal rotation and careful positioning of the implant played a crucial role in the success of this case, demonstrating the importance of precise planning and execution in implant dentistry.

A 60-year-old male patient presented to the clinic with complete edentulism in both the upper and lower arches. The patient had been edentulous for several years, leading to significant bone resorption and facial changes associated with the loss of alveolar ridge height and support. His primary concern was the restoration of both aesthetics and function, as the lack of teeth had compromised his ability to chew and affected his facial profile.
The complete edentulism presented several challenges, particularly related to the extensive bone resorption, which affected the stability and retention of conventional dentures. The patient's facial musculature had adapted to the edentulous state, making it essential to carefully manage the vertical dimension of occlusion (VDO) to avoid over-closure or an unesthetic appearance.
Additionally, ensuring the proper fit and comfort of the dentures required careful consideration of the remaining alveolar ridge anatomy. Achieving a balance between aesthetics, functionality, and patient comfort was paramount, especially given the potential for decreased retention and stability in cases of severe ridge resorption.
After a comprehensive assessment, it was decided to fabricate complete upper and lower dentures. A meticulous treatment plan was devised, beginning with accurate impressions and bite registration to ensure the proper establishment of the occlusal plane and VDO. The use of custom trays and border molding techniques was employed to capture the full extent of the available ridge, enhancing the retention and stability of the final prostheses.
The dentures were fabricated with attention to detail in the arrangement of teeth, ensuring that they complemented the patient’s facial structure and restored a natural appearance. The choice of teeth and gingival contouring was made to provide a lifelike appearance, while also restoring the patient’s ability to chew effectively. Special attention was given to the fit of the dentures to avoid any discomfort or irritation, particularly in areas with thin mucosa overlying the resorbed ridges.
The patient was highly satisfied with the results, reporting a significant improvement in both his ability to eat and his overall appearance. The dentures provided excellent retention and stability, despite the challenges posed by the resorbed ridges. The successful restoration of the patient’s oral function and aesthetics greatly improved his quality of life, underscoring the importance of a tailored approach in the management of edentulous cases.
The psychological impact of tooth loss is often underestimated in clinical practice, yet it can significantly affect a patient's self-esteem and overall well-being. Immediate dentures offer a valuable solution, allowing patients to transition more comfortably by replacing teeth at the same visit as the extractions. This approach not only minimizes the emotional distress associated with edentulism but also provides immediate functional and aesthetic benefits. In some cases, patients prefer the immediate denture to closely mimic the position and shape of their existing anterior teeth, rather than opting for a sudden transformation to a 'perfect' smile.
The construction of immediate dentures presents several challenges. Accurately predicting the post-extraction ridge contour and ensuring that the denture fits properly without adjustments can be difficult. Moreover, aligning patient expectations with clinical outcomes, especially when aiming to replicate the natural irregularities of their existing teeth, requires a careful balance of technical precision and aesthetic judgment. Ensuring that the denture provides sufficient retention and stability immediately after surgery is another key concern, given the changes in the oral environment that occur post-extraction.
Addressing these challenges involves meticulous planning and communication with the patient. A thorough pre-extraction assessment, including diagnostic impressions and bite registration, is essential for crafting a denture that fits well and meets aesthetic expectations. In some cases, a staged approach may be recommended, where minor adjustments are made after initial healing to optimize fit and comfort. Patient education is also critical, ensuring they understand the temporary nature of immediate dentures and the potential need for relining or replacement as the healing process progresses.
The successful delivery of immediate dentures can significantly enhance patient satisfaction, offering an immediate solution that addresses both functional and aesthetic concerns. Patients often express relief at not having to experience a period of edentulism, and the psychological benefits are notable. Follow-up care is crucial to monitor the fit of the dentures and make necessary adjustments, ensuring long-term comfort and functionality. This approach not only helps in maintaining oral health but also supports the patient's emotional well-being during what can be a challenging transitional period.
Survey crowns are a specialized restorative option that I was first introduced to during my training at UCLA. These crowns play a crucial role in optimizing abutment contours to achieve a more favorable design for Removable Partial Dentures (RPDs). They are particularly indicated for teeth with extensive restorations, endodontically treated teeth, or those with contours that cannot be adequately managed with enameloplasty. The process involves fabricating a wax-up of the survey crown, followed by re-surveying the cast to ensure that the contours of the wax-up align precisely with the predetermined design parameters for the RPD framework. This technique ensures that the final restoration supports the mechanical and aesthetic demands of the prosthesis.
The primary challenge with survey crowns lies in achieving the precise modification of abutment contours required for optimal RPD design. This necessitates a deep understanding of both prosthodontic principles and the specific mechanical needs of the RPD framework. Additionally, balancing the functional requirements of the crown with the aesthetic considerations can be difficult, especially in cases where the abutment teeth are in the esthetic zone. The risk of over-reduction or under-preparation of the tooth structure also presents a significant challenge, as it could compromise the structural integrity or the retentive capacity of the crown.
To address these challenges, a meticulous approach was adopted, beginning with a thorough diagnostic work-up that included radiographic analysis and detailed planning of the RPD design. The wax-up was carefully fabricated to meet the specific contour requirements, ensuring that it provided the necessary undercuts and guiding planes while preserving the esthetics and function of the abutment teeth. The cast was then re-surveyed to confirm that the final contours met the predetermined design criteria. This process was supported by close collaboration with the dental laboratory, ensuring that every step was executed with precision.
The final outcome was highly successful, with the survey crowns providing the necessary structural support and contour modification for the RPD. The crowns not only enhanced the retention and stability of the prosthesis but also met the aesthetic expectations of the patient. This case underscores the importance of integrating advanced restorative techniques with comprehensive prosthodontic planning to achieve optimal results in complex rehabilitative cases.
"It feels like natural teeth again" were the first words my patient uttered after receiving his implant-supported crowns. The patient had been using a removable partial denture (RPD) to replace his posterior teeth for the past five years. While implants have become increasingly popular among general practitioners, advancements in technology have significantly improved their osseointegration properties. However, implant failure rates have been rising over the past decade. Proper treatment planning and thorough preoperative workup are critical in enhancing the success rate and longevity of implants.
The primary challenge in this case was restoring all the posterior molars. On the right side, the patient had only the maxillary first molar remaining, so we focused on restoring just that molar with an implant-supported crown. This selective restoration required careful consideration of occlusal balance and functional load distribution to ensure long-term success and patient satisfaction.
To address the challenges, we conducted a comprehensive treatment plan that included detailed diagnostic imaging and occlusal analysis. The implant placement was meticulously planned to ensure optimal positioning, angulation, and depth, taking into account the limited space and existing occlusal scheme.

Removable Partial Denture (RPD) design is a critical aspect of restorative dentistry, involving various components that work together to restore function, aesthetics, and comfort for patients with partial edentulism. These components include major connectors, minor connectors, direct retainers, indirect retainers, and rests. Each element serves a specific purpose, ensuring the stability and retention of the prosthesis, while also distributing functional forces appropriately. The design of an RPD must be meticulously tailored to the individual patient's oral condition, requiring careful consideration of factors such as the number of remaining teeth, the condition of the supporting structures, and the patient's overall oral health.
One of the primary challenges in RPD design is the temptation to delegate this task entirely to a lab technician. While lab technicians are skilled in fabricating prostheses, the clinical perspective of a dentist is crucial in the design process. The dentist's understanding of the patient's oral anatomy, functional dynamics, and specific clinical needs allows for a more personalized and effective design. Additionally, each RPD case presents unique challenges; therefore, the design process is far from a one-size-fits-all approach. A standardized design could lead to poor fit, discomfort, and even damage to the remaining teeth or soft tissues.
The most effective approach to RPD design involves close collaboration between the dentist and the lab technician, with the dentist taking the lead in the initial design phase. This ensures that the RPD is customized to meet the patient's specific needs, with the dentist making informed decisions about the selection and placement of components. For example, the dentist can determine the most appropriate major connector based on the arch form and tissue conditions, select direct retainers that offer optimal retention without compromising tooth structure, and position rests to provide adequate support and prevent unwanted movement of the prosthesis. This collaborative approach not only improves the fit and function of the RPD but also enhances patient satisfaction and long-term oral health.
By prioritizing the dentist's role in RPD design, the final prosthesis is more likely to achieve its intended goals of restoring function, aesthetics, and comfort. Patients benefit from a prosthesis that is tailored to their unique oral condition, leading to improved retention, stability, and overall satisfaction. Moreover, the dentist's involvement in the design process reduces the risk of complications, such as tissue irritation or tooth damage, thereby contributing to better long-term outcomes. Ultimately, the success of an RPD hinges on the meticulous design process, which should be spearheaded by the dentist rather than delegated entirely to the lab technician
Open sinus lift procedures have become an indispensable technique in implant dentistry, especially when faced with insufficient vertical bone height in the posterior maxilla. This case involved a patient requiring dental implants in the upper molar region, where the maxillary sinus presented a significant challenge due to its proximity. The procedure was carefully planned using advanced imaging techniques to ensure precise and predictable outcomes.
The primary challenge was the reduced bone height in the posterior maxilla, with less than 3 mm of bone available for implant placement. Ensuring the integrity of the Schneiderian membrane during the procedure was also paramount, as any perforation could lead to complications such as sinusitis or graft failure.
A lateral window approach was selected for this open sinus lift procedure, allowing for direct visualization and careful elevation of the Schneiderian membrane. To enhance the bone regeneration process, a combination of autogenous bone and a xenograft material was used, promoting both osteoconduction and osteoinduction. Meticulous technique and the use of piezoelectric surgical tools were employed to minimize trauma and ensure the precise elevation of the sinus membrane. Antibiotic prophylaxis and postoperative care were carefully managed to reduce the risk of infection and ensure optimal healing.
The procedure was successful, with no complications reported during or after surgery. The bone graft integrated well with the native bone, providing a stable foundation for future implant placement. Follow-up radiographs showed significant bone gain in the maxillary sinus area, and the patient reported minimal discomfort postoperatively. This case highlights the effectiveness of an open sinus lift in managing complex cases with severe bone loss, paving the way for successful implant placement and long-term dental restoration.
