STATEMENT OF PROBLEM There is little information as to how the number and distribution of implants affect the amount of load transmitted to the palate in implant-retained maxillary overdentures. PURPOSE The purpose of this study was to evaluate the effect of the number and distribution of dental implants on the load transmitted to the palate. MATERIAL AND METHODS Eight implant analogues wer...

OBJECTIVES The effect of inter-implant distance on retention and resistance of implant-tissue-supported overdentures is lacking in the literature. An in vitro study was performed to evaluate this effect for mandibular implant-tissue-supported overdentures retained by two ball attachments. MATERIALS AND METHODS An acrylic cast of an edentulous mandible was fabricated. Three pairs of implants w...

Fabrication of implant-supported maxillary or mandibular overdentures can seem to be difficult procedures. Many things could go wrong and/or unnoticed until the fabrication has been completed. Implants must be correctly surgically placed in viable bone at the proper angulation and spacing within an arch. The type of attachment must be considered and future treatment of the appliance should be s...

Prospective clinical studies with the ASTRA TECH Implant System show that the survival rate of implants placed in the mandible is the same when comparing overdentures and fixed bridges, irrespective of retaining system used . The use of a ball abutment or a Locator for a non-splinted support, as well as the use of a bar attachment for a splinted support, is well documented with a followup of 1–...

Though totally implant-supported restorations are very successful, dentists may resort to prescribe implant overdentures because of functional, anatomical, economical or aesthetic considerations. However, the loading conditions of the partially implant-supported overdenture may affect the long term predictability of this type of restoration. The concept of the Andrew's bar system can be utilize...

Teeth loss is a traumatic experience. It disturbs the total integrity of masticatory system. Its successful rehabilitation should address range biomechanical problems, tolerances, and perceptions. Precision attachment-supported over Dentures with two teeth retained in canine region predictable treatment option edentulous mandible rather than conventional complete denture as it offers increased ...

This study compared the experiences with surgical procedures and treatment effects of a mainly implant-supported overdenture retained by a transmandibular implant with those of an implant tissue-supported overdenture retained by two cylindrical endosseous implants. Treatment had been assigned according to a balanced allocation method to 95 patients, including a control group who received only c...

The complexity of rehabilitation for totally edentulous patients makes it necessary to devise treatment strategies that meet the patients' expectations in terms of function, esthetic, psychological, and social aspects. The aim of this study was to i) compare the satisfaction of edentulous patients who had been rehabilitated with implant-supported overdentures and fixed prostheses in the mandibl...
