Multicenter randomized clinical trial: early loading of implants in maxillary bone.

Purpose: The aim of this study was to show prognostic equivalence between implant loading in the maxilla after 12 weeks versus 4 weeks.

Materials And Methods: One hundred four patients, from four centers in this open-labeled randomized multicenter prospective controlled clinical trial, were assigned to either 12 weeks or 4 weeks of unloaded healing. Two hundred sixty-nine implants (sand blasted large-grid, acid etched [SLA] surface, ≥ 4.

Minimally invasive esophagectomy: thoracoscopic esophageal mobilization for esophageal cancer with the patient in prone position.

Background: Surgical resection is the mainstay treatment for resectable esophageal cancer. Minimally invasive esophagectomy is performed with increasing frequency and proves to be a safe and effective surgical alternative to the open technique. Minimally invasive esophagectomy using thoracoscopic esophageal mobilization with the patient in prone position seems to offer some advantages with regard to surgeon ergonomics and clinical outcome.

Early loading of sandblasted and acid-etched titanium implants in the edentulous mandible: a prospective 5-year study.

Purpose: The aim of this prospective cohort study was to determine the 5-year implant survival and success rates associated with early loading (6 weeks after nonsubmerged placement) of sandblasted and acid-etched (SLA) Straumann implants in the edentulous mandible. A secondary objective was to determine the peri-implant tissue response and measure alterations in peri-implant crestal bone levels.

Materials And Methods: SLA implants were placed and primarily loaded 6 weeks later with 35 Ncm during abutment placement.

[Combined sinus lift procedure and lateral augmentation. A treatment concept for the surgical and prosthodontic rehabilitation of the extremely atrophic maxilla].

Purpose: This paper describes a surgical and prosthetic procedure for treating the extremely atrophic maxilla. It explains a two-staged surgical technique, donor and recipient site morbidity, implant survival, and the implant-retained prosthetic rehabilitation of the patients.

Patients And Methods: A total of 57 consecutive patients were treated with a sinus lifting procedure and a simultaneous lateral augmentation using autogenous corticocancellous block and particulate bone grafts from the iliac crest.

Anastomotic stenoses occurring after circular stapling in esophageal cancer surgery.

Background: Circular staplers have reduced the incidence of anastomotic leaks in esophagovisceral anastomosis. However, the prevalence of stenosis is greater with staplers than with manual suturing. The aim of this study was to analyze potential risk factors for the onset of anastomotic stenoses and to evaluate their treatment and final outcome.
