Allogeneic Bone Application in Association with Platelet-Rich Plasma for Alveolar Bone Grafting of Cleft Palate Defects.

Aim: The aim of this study is to compare allogeneic bone grafts associated with platelet-rich plasma (ALBGs-PRP) to autogenous bone grafts (ATBGs) for alveolar reconstructions in patients with cleft lip and palate (CLP).

Materials And Methods: The Maxillofacial Surgery Service of the Comprehensive Care Center for CLP (CCCLP) in Curitiba (Paraná, Brazil).

Patients: Thirty out of 46 patients with 8-12 years of age and pre- or trans-foramen unilateral clefts were operated by the same surgeon.

Treatment of odontogenic myxoma: a multidisciplinary approach-6-year follow-up case.

The most aggressive diseases that affect the oral environment are considered tumors of the jaw. The surgical treatment is preferably done by surgical resection of the lesion, resulting in a great loss of tissue and esthetics. Multidisciplinary planning is required for the rehabilitation of these cases.

Medial canthal region as an external reference point in orthognathic surgery.

Purpose: The aim of this investigation was to evaluate the effectiveness of using the medial canthal region (MCR) as an external reference point to determine the vertical dimension during maxillary repositioning as planned in model surgery and predictive tracing.

Materials And Methods: The analyzed group consisted of 43 consecutive patients who underwent maxillary or bimaxillary orthognathic surgery. Before downfracture, the vertical height was established from the distance of the MCR to the incisal edge of the right upper central incisor (UCI).

Analysis of 185 maxillofacial fractures in the state of Santa Catarina, Brazil.

A retrospective study was performed to assess maxillofacial fractures in patients treated at a public hospital from 2002 to 2006. The data collected included age, gender, etiology, type of injury, treatment modalities and period of treatment. Causes were grouped into seven categories: road traffic collisions, sports accidents, occupational accidents, gunshot fractures, falls, violence and other causes.

Analysis of 40 cases of intraoral verticosagittal ramus osteotomies to treat dentofacial deformities.

Purpose: The aim of the present study was to report the experience of 40 patients who had undergone intraoral verticosagittal ramus osteotomy (IVSRO) to treat dentofacial deformities.

Patients And Methods: The charts of 40 consecutive patients who had undergone IVSRO were analyzed regarding the diagnosis, amount of mandibular movement, and complications.

Results: Eighty IVSROs were performed in 40 patients.

Surgically assisted palatine expansion in adult patients: evaluation of a conservative technique.

Purpose: This study was conducted to assess a conservative technique for surgically assisted palatine expansion (SAPE) done under local anesthesia and conscious sedation in adults. Dental inclination, uniformity of expansion, and satisfaction of orthodontist were evaluated.

Patients And Methods: Twenty-seven consecutive patients, ranging in age from 25 to 42 years, underwent SAPE under local anesthesia.

Histomorphometric evaluation of alumina-blasted/acid-etched and thin ion beam-deposited bioceramic surfaces: an experimental study in dogs.

Purpose: In an attempt to overcome the potential long-term limitations observed with plasma-sprayed hydroxyapatite-coated implants, nanothickness bioceramic coatings have been processed onto previously grit-blasted/acid-etched surfaces. Our objective was to evaluate the bone response to alumina-blasted/acid-etched and a thin ion beam-deposited bioceramic (Test) implant surfaces at 2 and 4 weeks in vivo with a dog tibia model.

Materials And Methods: Plateau root form implants (5 x 6 mm) were placed bilaterally along the proximal tibia of 6 Doberman dogs and remained for 2 and 4 weeks in vivo (n=6 per implant type and time in vivo).
