Comparison of posterior residual ridge resorption in patients wearing conventional denture, two implant-retained mandibular overdenture and four implant-supported overdenture: a 5-year retrospective study.

Anterior maxillary residual ridge resorption and posterior residual ridge resorption in patients with an implant-retained mandibular overdenture compared to patients with a conventional mandibular denture; a 10-year prospective study

Posterior mandibular residual ridge resorption in patients with conventional dentures and implant overdentures.

PURPOSE This study investigated the effects of certain systemic and local factors on resorption of the posterior mandibular residual ridge under conventional dentures and overdentures supported by 2 implants. MATERIALS AND METHODS Proportional area measurements of the posterior mandible were made on rotational tomograms taken immediately before and 5 years after treatment. The area was bounde...

Radiographic and surgical guide fabrication for implant-retained mandibular overdenture.

A simple technique is presented to make a multipurpose duplicate of the patient's complete denture to plan and fabricate a mandibular implant-retained overdenture. This duplicate serves 3 different functions. It can be used as a radiographic guide, surgical template, and custom tray adapted to the patient's occlusion. Advantages of the technique described are twofold: it is cost effective and m...

Comparative evaluation of peri-implant tissues in patients wearing mandibular overdenture with different implant platforms

Background The poor hygiene of peri-implant tissues causes inflammation at tissue-implant interface, which may impair the rehabilitation success. The aim of this study was to evaluate the influence of external hexagon and Morse taper implants on peri-implant health in patients wearing mandibular overdentures for 1 year. Materials and Methods A total of 46 implants were evaluated, 28 external ...

Soft liner-retained, implant-supported overdenture: a technical note.

This paper describes the design and fabrication of a soft liner-retained, implant-supported overdenture used in 10 patients over a period of 1 to 6 years. A final complete denture impression is made of the dental arch, including implant abutments extending 5 mm above the gingival tissue. The master cast is fabricated with actual abutments placed in the impression. After the final wax try-in, th...
