Treatment planning for dental implant patients is often complicated by the unknown extent of the anterior loop of the mental neurovascular bundle. The aim of this study was to determine the correlation between the visual interpretation of the panoramic radiographs and the anatomical dissection findings in a cadaveric sample. Panoramic radiographs of the 22(More)
The aim of this study was to compare the success rates after 1 and 2 years of conventionally and early loaded pairs of unsplinted ITI implants supporting mandibular overdentures in edentulous patients. Twenty-four participants (age range 55-80 years) were randomly allocated with maximum concealment to two treatment groups. In the first group, the implants(More)
BACKGROUND Maxillary implant overdentures opposing mandibular two-implant overdentures are an underused treatment option for edentulous patients. Fewer implants, simple surgery, and short healing periods may increase patients' acceptance of this treatment concept. PURPOSE To determine implant success, after overdenture loading, of three narrow-diameter(More)
PURPOSE Degradation products of metallic biomaterials including titanium may result in metal hypersensitivity reaction. Hypersensitivity to biomaterials is often described in terms of vague pain, skin rashes, fatigue and malaise and in some cases implant loss. Recently, titanium hypersensitivity has been suggested as one of the factors responsible for(More)
BACKGROUND Step-wise reduction in loading protocols is necessary to evaluate early loading of implants with mandibular overdentures. PURPOSE To compare the success rates of two different dental implant systems following conventional or early loading protocols in patients being rehabilitated with mandibular overdentures. MATERIALS AND METHODS Forty-eight(More)
BACKGROUND Patient-based outcomes with maxillary overdentures on a minimum number of implants, opposing mandibular 2-implant overdentures are not evident in the literature. PURPOSE To evaluate patient's satisfaction with maxillary 3-implant overdentures, opposing mandibular 2-implant overdentures, using two different attachment systems over the first 2(More)
PURPOSE Resonance frequency analysis (RFA) is used to measure oral implant stability. There is controversy with regard to its accuracy in predicting both implant stability and osseointegration. This systematic review and meta-analysis determined the prognostic accuracy of RFA in predicting implant failure following immediate loading protocols. MATERIALS(More)
PURPOSE A prospective study on mandibular implant-supported overdentures using more than 2 Brånemark implants splinted with multiple round bars evaluated a hypothesis that unnecessary prosthodontic maintenance would result from the contravention of accepted biomechanical principles. MATERIALS AND METHODS A randomized prospective trial on 59 edentulous(More)
This study investigated the path of emergence of the mental nerve in a number of human population groups. Skeletal material comprised 117 Negro skulls (53 males), 114 caucasoid skulls (62 males) and 100 pre-contact Maori skulls (70 males). In each case, the path of emergence was classified into posterior, anterior, right-angled or multiple. Those cases with(More)
PURPOSE The aim of this research was to determine the long-term prosthodontic maintenance requirements of mandibular two-implant overdentures using different loading protocols and attachment systems. MATERIALS AND METHODS A total of 106 participants were allocated randomly to one of four different implant systems (Steri-Oss, Southern, Straumann, or(More)
