Insufficient bone quality and quantity in posterior maxilla is a common clinical state, which leads to further prosthetic surgery difficulties. It occurs on account of several causes, most frequently due to the pneumatization of sinus subsequent to the tooth loss and the concomitant excessive alveolar resorption [1]. Depleted alveolar bone is insufficient to host implants of 10 mm in length and...

PURPOSE To assess the relevance of simultaneous sinus-lift and implantation with leukocyte- and platelet-rich fibrin (L-PRF, Choukroun's technique) as sole subsinus filling material. MATERIALS Twenty-three lateral sinus elevations (SA4 sinus) were performed on 20 patients with simultaneous implant placement. Seven patients were treated with 19 Astra implants (AstraTech, Mölndal, Sweden) and 1...

The effects of a soft tissue mobilization procedure, the Rolfing pelvic lift, on parasympathetic tone was studied in healthy adult men. Parasympathetic tone was assessed 1) by quantifying the amplitude of the respiratory sinus arrhythmia from the heart rate pattern and 2) by measuring heart rate. Heart rate patterns were assessed during the pelvic lift and during the durational touch and baseli...

Restoration of the posterior maxilla with reduced bone height and pneumatized sinus is a challenge to the implant surgeon. The surgeon has the option of a direct sinus-lift approach or an indirect blind approach. Both of which have its own complications. Displacement of an implant into the maxillary sinus is rare occurrence and normally seen after the implant has been in service for a number of...

A literature review is made to analyze the survival of implants placed with the osteotome technique. A PubMed search was made based on the key words "osteotome AND dental implants", corresponding to publications between 1998-2008. The inclusion criteria were: a) a minimum of 10 patients; b) a minimum follow-up of 6 months; c) implants placed using the osteotome technique with or without indirec...
