Autogenous Dental Transplantation in a Patient Undergoing Class III Dento-Facial Deformity.

Dental transplantation is an alternative for rehabilitation with a high success rate. This article presents a clinical case of autogenous dental transplantation in a 17-year-old male patient undergoing treatment for Class III dento-facial deformity. After 32 months followup, low-cost rehabilitation was possible, and without prejudice to ortho-surgical treatment.

Horizontal ridge augmentation using xenogenous bone graft-systematic review.

Purpose: This study aimed to perform a systematic review about the use of xenogenous bonegraft in horizontal ridge augmentation to answer the following question: In implant patients, treated with xenografts for horizontal ridge augmentation, what would be the outcomes in terms of bone gain, bone resorption, implant survival, and complication rates?

Methods: The main search was performed at PubMed, Cochrane, and Scopus databases, and found 2610 articles. After selection and duplicate removal, 29 studies were included in the final review. The collected data were sample size, number and type of graft, site, horizontal gain, resorption rate, and complications.

Titanium mesh associated with rhBMP-2 in alveolar ridge reconstruction.

A systematic review of the literature was performed regarding the use of titanium mesh in association with recombinant human bone morphogenetic protein (rhBMP) for alveolar ridge reconstruction. The PubMed, Scopus, and Cochrane databases were searched for articles in English published up until June 2017. The inclusion criteria encompassed studies in humans - randomized clinical trials, prospective and retrospective studies, and case series.

Buccal fat pad removal to improve facial aesthetics: an established technique?

Background: Buccal fat pad (BFP) is a singular structure between the facial muscles. Its removal may enhance the zygomatic prominences resulting in an inverted triangle of beauty.

Objective: The aim of this study was to perform a systematic review of literature about BFP removal for facial aesthetic improvement.

Mandibular Reconstruction by Osteogenic Distraction Due to Two Different Injuries.

Varied factors, whether intrinsic or extrinsic, may lead to a decrease in the bone volume of the jaws. Trauma and pathology can be listed as examples of such factors. The aim of this study is to present the osteogenic distraction technique as alternative to augmentation of low mandibular bone volume caused by different etiologies.

Nasal airway evaluation in obstructive sleep apnoea patients: volumetric tomography and endoscopic findings.

Obstructive sleep apnoea (OSA) results from the recurrent collapse of the upper airway during sleep. Nasal abnormalities influence the stability of the pharynx. The aim of this study was to evaluate the volumetric and anatomical changes of the nasal cavity in patients with OSA.

Surgical Resolution of Bilateral Hypertrophy of Masseter Muscle Through Intraoral Approach.

Masseter muscle hypertrophy is an untypical anomaly with no definite cause and its diagnosis is easily completed through physical examination and imaging examinations. In some cases, patient may report signs and symptoms of well-localizated pain. However, it is generally asymptomatic and patient's chief complaint is about esthetic because of facial asymmetry.

The relevance of dental surgeon on Gorlin-Goltz syndrome.

Multiple odontogenic keratocysts could be linked to different conditions. Then, to achieve the correct diagnosis whether their presence is associated to a syndrome, some criteria must be followed. The present study aims to report a case of a 21 years-old male patient whose was referred with several radiolucent lesion on the maxilla-mandibular complex.

Porous Polyethylene Implant as Aesthetic Complement in Orthognathic Surgery.

Porous polyethylene implants have been used as an alternative in the treatment of patients with zygomatic and paranasal projections deficiency. These implants promote a facial rejuvenating effect due to the attenuation of the nasal and chin prominences. The advantages of porous polyethylene include biocompatibility, dimensional stability, easy adaptation and fixation, low complication rate, and its availability in different sizes and shapes.

The Importance of Early Diagnosis of Retrobulbar Hemorrhage.

Midface fractures usually affect the orbital cavity. This trauma may result in severe and rare consequences such as retrobulbar hemorrhage. This condition requires immediate diagnosis and early intervention to avoid blindness.

Evaluation of the palatal split pattern in surgically rapid maxillary expansion-comparison of two techniques.

Purpose: Surgically assisted rapid maxillary expansion is performed to correct transverse deficiencies of the maxilla, and it is indicated in specific clinical situations. The literature presents different opinions in several aspects, mainly regarding the effect of disjunction of the pterygoid plates. The aim of this study was to evaluate the pattern of maxillary expansion obtained with two surgical techniques, with and without disjunction of the pterygoid plates.

Bone Ceramic® at Implants Installed Immediately into Extraction Sockets in the Molar Region: An Experimental Study in Dogs.

Purpose: The aim of this paper was to study the healing of 1-1.4 mm wide buccal defects at implants placed immediately into extraction sockets (IPIES) filled with a mixture of synthetic hydroxyapatite (HA) 60% and beta-tricalciumphosphate (TCP) 40% or left with the clot alone and both covered with collagen membranes.

Material And Methods: Eight Labrador dogs were used and implants were placed immediately into the extraction sockets of the first molar bilaterally.

Implant-supported rehabilitation after treatment of atrophic mandibular fractures: report of two cases.

Objective: The objective of this article is to present options of rehabilitation with dental implants in two cases of severely atrophic mandibles (<10 mm) after rigid internal fixation of fractures.

Patients And Method: Two patients who sustained fractures in severely atrophic mandibles with less than 10 mm of bone height were treated by open reduction and internal fixation through a transcervical access. Internal fixation was obtained with 2.

Correlation between the Friedman Staging System and the upper airway volume in patients with obstructive sleep apnea.

Purpose: This study was designed to evaluate the correlation between computed tomography findings and data from the physical examination and the Friedman Staging System (FSS) in patients with obstructive sleep apnea (OSA).

Patients And Methods: We performed a retrospective evaluation by reviewing the medical records of 33 patients (19 male and 14 female patients) with a mean body mass index of 30.38 kg/m(2) and mean age of 49.

Utilization of autogenous bone, bioactive glasses, and calcium phosphate cement in surgical mandibular bone defects in Cebus apella monkeys.

Purpose: The purpose of the present study was to evaluate the histologic results of bone cavities that were surgically created in the mandibles of Cebus apella monkeys and filled with autogenous bone, PerioGlas, FillerBone, or Bone Source.

Materials And Methods: Surgical cavities 5 mm in diameter were prepared through both mandibular cortices in the mandibular angle region. The cavities were randomly filled, and the animals were divided into groups according to the material employed: Group 1 cavities were filled with autogenous corticocancellous bone; group 2 cavities were filled with calcium phosphate cement (BoneSource); and group 3 and group 4 cavities were filled with bioactive glass (FillerBone and PerioGlas, respectively).
