Maxillary all-on-four therapy using angled implants: a 16-month clinical study of 1110 implants in 276 jaws.

The maxilla is a challenging area for dental implant restoration. Encroachment of anatomic structures such as the sinus and nasal floor make vertical placement difficult. Implants placed at an angle may be used to avoid these anatomic structures or eliminate the need for a bone grafting procedure.

[Effects of removable partial dentures on the quality of life in people with shortened dental arches].

In order to assess the enhanced value of removable partial dentures on the quality of life, patients at 2 university clinics were screened for the presence of complete or shortened dental arches. Those selected were assigned to 1 of 5 subgroups: 1) a shortened dental arch with all frontal teeth, 2) a shortened dental arch with one or more frontal diastemas, 3) a shortened dental arch with all frontal teeth, restored by a removable partial denture, 4) a shortened dental arch and several diastemas, restored by a removable partial denture, 5) a complete dental arch. The participants completed the Oral Health Impact Profile (OHIP-49) and the Short Form Health Survey (SF-36).

Effect of removable partial dentures on oral health-related quality of life in subjects with shortened dental arches: a 2-center cross-sectional study.

Purpose: To assess the value of removable partial dentures (RPDs) in subjects with shortened dental arches (SDAs) with regard to quality of life.

Materials And Methods: Subjects from 2 university dental centers (82 men, 78 women; mean age: 54 +/- 18 years) were categorized into the following groups: (1) SDA with intact anterior regions (SDA-1, n = 44); (2) SDA and interrupted anterior region (SDA-2, n = 21); (3) SDA (intact anterior region) extended with distal-extension RPD (RPD-1, n = 25); (4) subjects with interrupted SDA and interrupted anterior region treated with RPD (RPD-2, n = 32); or (5) complete dental arches (CDA, n = 38) as a control. All subjects underwent a short clinical examination and completed 2 structured questionnaires: the Oral Health Impact Profile (OHIP-49) and the Short-Form Health Survey (SF-36).

Screw-retained prosthesis for Straumann implant sites with limited interocclusal clearance.

This article reports a technique that addresses the problem of the restricted interocclusal distance when screw-retained prostheses are selected.
