Review
OBJECTIVES
To review the literature on mandibular single-implant overdentures (opposing complete maxillary dentures), and present surgical and prosthodontic perspectives of a novel approach for this treatment option.
MATERIAL AND METHODS
An electronic search through the databases of Pubmed, Embase and Medline using the linked key words 'mandibular single implant overdentures' was performed. The search was limited to English language articles published up to August 2008. Hand searches through articles retrieved from the electronic search, peer-reviewed journals and recent conference proceedings were also conducted.
RESULTS
A limited number of reports were identified on mandibular single-implant overdentures (opposing maxillary complete dentures). They comprised of case-series reports, short-term prospective trials and current randomized-controlled clinical trials. Different loading protocols with different implant systems have been used, but always with regular diameter implants. Specific anatomical and vascular dangers of the mandibular midline symphysis are identified including a novel surgical approach using a currently available short, wide diameter tapered implant. In addition, the prosthodontic rationale for using a larger attachment system (incorporating a platform switch) for mandibular single-implant overdentures is described.
CONCLUSION
The review reveals that there is a lack of published randomized clinical trials using mandibular single-implant overdentures, opposing maxillary complete dentures. Without the evidence from randomized clinical trials, routine use of this novel approach cannot be recommended, compared with using regular diameter implants and matching attachment systems.

Since the introduction of milled zirconia copings for ceramic crowns, a variety of techniques have been introduced to reduce the incidence of chipping or fracturing of the porcelain veneer. These include methods of improving the interface between the coping and the veneer, reducing thermal incompatibility between the two, and optimizing the coping design to minimize tensile loading on the porcelain. Another method of reducing porcelain chipping and fracture is to limit or eliminate the porcelain coverage of zirconia copings and frameworks. Even though patients often demand tooth colored or nonmetallic restorations, they tend to be less concerned with the optimal esthetics of their posterior teeth. This article describes 4 representative clinical situations where efforts were made to minimize or eliminate porcelain coverage on posterior zirconia crowns and a fixed dental prosthesis, while still achieving acceptable, but not optimal, esthetics.

Comparative Study
Prostheses can be attached to implants or implant abutments by screw retention, cementation, or with the use of set-screws. The indications for non-screw-retained restorations are discussed with respect to implant body position and surgical limitations for implant placement. The advantages and disadvantages of each method are outlined. A technique that uses a screw threaded into the implant restoration to displace the cemented restoration is presented. Use of this technique will allow predictable removal of the cemented restorations without damage to the prosthesis or abutment.

The use of systematic terminology for implant prostheses can simplify communication within the scientific community. However, a review of the current literature demonstrates the lack of uniformity in this field. It is the purpose of this manuscript to suggest uniform terminology based on conventional prosthodontic terms that will simplify communication in the profession.

The accurate transfer of the subgingival contours of implant-supported restorations and pontics is essential for providing the dental technician with the necessary information to fabricate an optimal definitive fixed dental prosthesis. However, once the interim restoration is removed to make an impression, the subgingival tissue, which is no longer physically supported, tends to collapse. This digital intraoral and extraoral scanning technique offers a way to transfer the subgingival contours and intaglio surface of the interim restoration to the definitive restoration. In addition, this technique can reduce clinical and laboratory time, as well as the necessity of storing gypsum casts.

An implant fracture may be one of the major causes of late implant failures. Complications, such as loosening or fracture of the prosthesis restorative components, or even fracture of the implant, may occur and dental professionals should be aware of the causes of these complications. This study reports a clinical situation involving a patient restored with a mandibular overdenture that presented a fractured implant 2 years after placement. The probable cause of the implant fracture was due to biomechanical overload caused by parafunctional habits. The implant head was flattened to make it smooth, retapping the internal screw, installing a new abutment (longer), and fabricating part of the overdenture bar. This treatment was timesaving for the patient in that the prosthesis was repaired in the shortest time possible.
