Changes in facial profile after maxillomandibular advancement surgery for obstructive sleep apnea syndrome.

Unlabelled: The aim of this study was to assess changes in the profile of adult male patients treated for obstructive sleep apnea syndrome (OSAS) with maxillomandibular advancement (MMA) surgery and to measure patient perception of changes compared with that of different panels.

Materials And Methods: Fifteen consecutive apneic patients displaying a wide variety of morphological types, mean age 42 years (20-59), a BMI of 26.60 kg/m(2) (22-29), a mean initial Apnea Hypopnea Index (AHI) of 50.

[Mapping mini-implant anatomic sites in the area of the maxillary first molar with the aid of the NewTom 3G® system].

Introduction: The goal of our study was to construct a map of the implant sites in the region of the attached gingiva around the maxillary first molars that would be appropriate locations for placement of miniscrews to serve as orthodontic anchorage.

Method: We conducted 58 radiographic examinations with the NewTom 3G(®) cone beam technique. For each interdental space, between upper second bicuspids and first molars (5/6) and between upper first and second molars (6/7), we studied the mesio-distal width and depth of bucco-lingual bone at two different levels, L1 and L2, that corresponded to the lower and upper limits of the attached gingiva in the general population.
