The "hybrid abutment": a new design for implant cemented restorations in the esthetic zones
The international journal of esthetic dentistry, 2015
Cemented implant restorations are widely used by many dentists. The traditional abutment design resembles a natural tooth prepared for a crown with a similar taper and a chamfer finish line. A frequent complication associated with implant restorations in the esthetic zones is the recession of buccal gingiva over time. Abutment morphology, among several other prosthetic factors, may play an important role in the stability of the gingival margin in esthetically sensitive areas, but this has never been thoroughly analyzed. Recently, a prosthetic technique called biologically oriented preparation technique (BOPT) has been proposed, which utilizes a feather-edge preparation on natural abutments, and it has been claimed that applying the concepts of this technique to implant abutments could improve long-term gingival margin stability. At present, there is no available evidence to confirm this claim. Moreover, some concerns may arise if this particular design is implemented in every clinic...

Successful dental implant therapy in the maxillary anterior dentition requires meticulous attention to surgical and prosthodontic measures. Proper diagnosis, extraction technique, implant selection, and placement significantly impact outcomes. Respect of hard and soft tissue physiology following tooth loss and implant placement requires specific steps be taken. Management tissue contours properly, via regenerative therapy, results in successful framing of the restoration. Provisionalization and definitive restorative therapy also impacts the level of esthetic success. The contours of the temporary abutment and crown develop soft tissue contours for the final restoration. Overcontouring can lead to soft tissue recession and mucosal asymmetry. Design of the definitive crown(s) is crucial for long-term maintenance of esthetically acceptable results. Visualizing the outcome of treatment prior to its inception, following specific surgical and restorative guidelines, increases the likelih...
Gingival Reshaping Using Provisional Restoration in a Maxillary Anterior Implant - A Case Report
Journal of Nepalese Prosthodontic Society, 2020
Oral implants are regarded as one of the most successful and reliable treatment options for replacing missing tooth/teeth. Various studies have reported that it can be used to meet the functional as well as esthetic demands of missing teeth. The most common indication of oral implants is the replacement of single or multiple teeth to support the denture. While replacing teeth in the esthetic zone, then consideration should be towards creating the right emergence profile. So, replacing a tooth with the implant-supported prosthesis in the anterior region is more challenging as compared to the posterior. With clinical examination, radiographic investigation, and treatment planning good results can be achieved. This case report highlights the placement of a single-tooth dental implant in the anterior region where the emergence profile was created with gingival moulding similar to that of adjacent gingiva using provisionalization.

Conclusion: Visualizing the outcome of treatment prior to its inception, following specific surgical and restorative guidelines, increases the likelihood of success.
Aesthetic Approach in Single Immediate Implant-Supported Restoration
Journal of Craniofacial Surgery, 2010
The aim of this study was to analyze the main aspects that influence the aesthetics of single immediate implant-supported restorations through a literature review on the MEDLINE database. It was observed that immediate implant-supported restorations present clinical success with aesthetic predictability demonstrated by the literature. Proper patient selection and diagnostic and multidisciplinary planning are essential and should be associated to technical ability of professional and knowledge concerning the biology of periimplant tissues. It is suggested that provisional restoration should be immediately inserted after implant fixation to guide healing of gingival tissues with a proper emergence profile besides psychologic comfort for a patient due to immediate aesthetic reestablishment.
Transfer of Esthetic Gingival Contour for Anterior Implant Prosthetics
International Journal of Oral Implantology and Clinical Research, 2011
Communication of the exact positioning of the gingival margin is critical to achieving anterior esthetics with implant fixed prosthetics. The time taken to shape and position the gingiva with a provisional restoration can be lost at the impression appointment. Upon removal of the provisional restoration, the gingival complex collapses lossing positioning and hampering the laboratory in fabrication of the final restoration. This article shall review a technique to replicate and communicate the soft tissue positioning and support to the laboratory using custom impression copings, allowing better esthetics with the restoration upon placement.
Implant Abutment: A Vital Link in the Success of Implant Restoration
International journal of health sciences and research, 2024
Dental implants serve as a vital solution for replacing missing teeth. They offer excellent support for both fixed and removable prostheses, enhancing function and aesthetics. Understanding the biomechanics related to dental implant therapy is crucial, and one critical aspect is the selection of implant abutment. Due to increase in the availability of implant therapeutic components, the selection of an appropriate dental implant abutment for a given clinical situation has become extremely challenging. There are essential key factors to be kept in mind while making selection for an implant abutment. Different types of implant abutments are available in various categories based on different factors like retention (screwretained, cement-retained) ,angulations (straight or angled),design(stock, custom, CAD/CAM-milled) and fabrication (prefabricated or custom-made).Aim of this article is to discuss different categories of implant abutments to make the implantologist updated about the different implant abutment options available in the market and to empower them to make informed decisions and deliver optimal care to their patients whether it's a single tooth restoration or more complex ones, for long-term success of treatment
