Buccal periosteal inversion (BUPI) for defect closure and keratinized gingiva width preservation after tooth extraction - technique modification.

Introduction: Several techniques and methods have been proposed to cover alveolar bone after tooth extraction when soft tissue is lacking. Some authors recommend soft tissue flap techniques, and others advocate different types of materials for socket covering. In this article, the authors use a modified buccal inversion technique for adequate coverage of the alveolar ridge to ensure its preservation and to minimize soft tissue shrinkage and loss of keratinized gingiva after tooth extraction.

Particulated wisdom teeth as an autologous bone substitute for grafting/filling material in bone defects: Case Report.

Introduction: Bone augmentation material using permanent teeth are confirmed in many articles to provide good histological and clinical results. Advances in osteoconduction and osteoinduction, low cost of material, no risk of disease transmission and elimination of foreign body reaction are important aspects not only to the clinician but to patient as well. Many techniques and devices to obtain graft material for bone augmentation out of teeth are found in the literature.

Airway space changes after nasopharyngeal adenoidectomy in conjunction with Le Fort I osteotomy.

Purpose: The purpose of the present study was to evaluate the nasopharyngeal airway changes after transnasal adenoidectomy and to determine whether a specific facial morphologic type is associated with hypertrophied nasopharyngeal adenoids. The nasopharyngeal adenoid tissues are present during childhood but usually spontaneously atrophy by 12 to 14 years of age. However, some patients have hypertrophied nasopharyngeal adenoid tissues that can remain after 14 years of age and can cause dysfunction of the eustachian tubes, cause nasal airway obstruction, affect speech, and adversely alter facial growth.
