Abstract
The purpose of this study was to ascertain whether simplifying mandibular overdenture treatment utilising single stage surgery and immediate prosthetic loading of a single implant, will achieve similar implant success rates and functional improvement to that expected using conventional techniques. As part of this study, the Mk III Branemark implant with an oxidised surface (TiUnite [trademark] Nobel Biocare AB, Göteborg, Sweden) was compared to the classical machined Mk III Branemark fixture.Materials and Methods: 35 patients with a mean age of 68 years and problematic mandibular dentures were treated. The primary complaints among the patients referred to the clinic for treatment related to poor retention of the mandibular denture, instability, denture sores and phonetic problems. Patients were initially placed randomly into the 'machined surface' or 'oxidised surface' group. A single implant was placed into the mandibular midline with high initial stability. A ball attachment was placed and the retentive cap incorporated into the existing denture. Reviews took place at 3,12 6 6 and 36 months. Clinical assessments, radiographs made with custom film holders, and stability measurements by both manual and resonance frequency analysis methods were recorded. All complications, failures, maintenance and reasons for dropout were noted. Visual analogue scale questionnaires were utilised to record patient satisfaction. (ANOVA p
