Replacement of A Mandibular Molar with Implant Retained Single Crown
نویسندگان
چکیده
Among various challenges to restore a single tooth implant in the posterior region of the oral cavity is the creation of harmonious gingival contour beneath the restoration and near the abutment –gingiva interface so as not to allow plaque accumulation within this inaccessible zone. Deficiencies in the soft or hard tissue in the edentulous space are usually the most common obstacles to achieve a gingival symmetry around the proposed restoration, besides the factors like accessibility of cleansing aids to the area. This article describes a novel approach to eliminate the ridge or soft tissue deficiencies by over contouring and undermining soft tissue around the healing abutment at the second stage implant surgery.

Finite element analysis of three designs of an implant-supported molar crown.
STATEMENT OF PROBLEM The optimal method of implant support for a single mandibular molar crown is controversial because commonly used, threaded, root-form implants developed by Branemark were not originally designed to support individual crowns. PURPOSE The purpose of this study was to develop a finite element model of a single mandibular first molar crown supported by (1) a standard 3.75-mm-...

متن کاملCase Report Replacement of a Single Missing Tooth With an Implant - Supported Patient - Specific
Treatment of a single hopeless tooth is a routine challenge in dentistry. Causes for this condition commonly include traumatic injury, advanced caries and/or periodontal disease, and failed endodontic procedures. When adequate bone exists at a hopeless tooth site, the current standard of care is surgical extraction of the tooth, followed by placement of a dental implant and eventual restoration...
متن کاملStress distribution pattern of screw-retained restorations with segmented vs. non-segmented abutments: A finite element analysis
Background. Screw-retained restorations are favored in some clinical situations such as limited inter-occlusal spaces. This study was designed to compare stresses developed in the peri-implant bone in two different types of screw-retained restorations (segmented vs. non-segmented abutment) using a finite element model. Methods. An implant, 4.1 mm in diameter and 10 mm in length, was placed in t...
