study was 4 mm, whereas that of Yoon et al.’s study was 1.2 mm. A study by Geurs et al. found a significant difference in implant loss when residual bone height was less than 4 mm, as compared to 5 mm or greater. The authors should not have drawn a conclusion solely based on one other similar study. The referenced study by Jurisic et al. is not the same as the study done by Yoon et al., and thu...

A 46 year old woman presented with sudden onset severe, tight, central chest pain. She had stopped smoking 10 years previously, but there were no other cardiac risk factors. The ECG showed sinus rhythm with marked ST elevation over the anterior chest leads, and she received intravenous tPA within two hours of symptom onset. Despite thrombolysis, diamorphine, and intravenous â blockade, the pain...

OBJECTIVE To investigate whether patterns of swallowing difficulties were associated with the location of the brain lesion, cognitive function, and severity of stroke in stroke patients. METHOD Seventy-six patients with first-time acute stroke were included in the present investigation. Swallowing-related parameters, which were assessed videofluoroscopically, included impairment of lip closur...

The maxillary sinuses impose an important influence on partially or fully edentulous maxillary rehabilitations with dental implants. In a rehabilitation process with implants the space to place a dental prosthesis over an implant may be jeopardized by the remaining space between the dental arches. Because of this small space, an alveolar crest onlay bone graft is unlikable to be made. However i...

background and aim:  although there have been substantial developments in dental implant therapies, achieving good implant stability (isq >60) for implants inserted in augmented sinus sites appears to be challenging in comparison with non-augmented sites due to the high prevalence of bone resorption in posterior regions of maxilla. this study aimed to evaluate and compare the time required to a...

OBJECTIVES To compare the different variations of sinus elevation techniques with osteotomes, to evaluate the increase in height achieved, and to quantify the osseointegration periods and the success rates for the implants placed. STUDY DESIGN A meta-analytic study with descriptive statistics was carried out on sinus elevations using osteotomes, analyzing a total of 11 articles published betw...

The aim of this retrospective study was to report preliminary outcomes of a modified technique for transcrestal sinus floor elevation with simultaneous implant placement. A total of 165 implants were placed in 110 patients using a modified Summers technique. During implant site preparation, after fracturing the sinus floor, a small perforation of the membrane was made using the first osteotome....
