Gingival Biotype and Its Relationship With the Maxillary Membrane and Lateral Wall Thickness.

The purpose of this study was to analyze the risk of the maxillary sinus lift technique and the correlation between the thickness of the gingiva, maxillary sinus membrane, and the maxillary sinus lateral wall. Cone-beam computerized tomograhy (CBCT) records of 32 adult dentate patients (10 male/22 female) were analyzed. The gingival thickness records of the dental units were compared with the thickness measurements of the membrane and lateral wall of the maxillary sinus.

Anatomic study for the horizontal cut of the sagittal split ramus osteotomy.

Purpose: The purpose of this study was to determine the posterior extension of trabecular bone and the height at which both the lateral and medial cortical bone layers of the mandibular ramus merge, using a reference point on the anterior margin of the mandibular ramus.

Materials And Methods: A total of 80 adult human mandibles were studied. Starting at reference point X, we marked a line running from the anterior margin to the posterior margin of the mandibular ramus on the medial aspect of the study samples.

Direct and tomographic dimensional analysis of the inter-radicular distance and thickness of the vestibular cortical bone in the parasymphyseal region of adult human mandibles.

We calculated the inter-radicular distances between the canine, and first and second premolars, of human mandibles and the thickness of the cortical bone at adjacent sites using computed tomographic (CT) imaging, and assessed the precision of the dimensional assessment made by CT compared with the same measurement made directly with calipers. We examined 100 adult cadaveric dentate human hemimandibles. At the level at which monocortical screws are inserted to place miniplates according to the current technique used to treat mandibular fractures, points A, B, and C referred to the canine, and first and second premolars, and were marked to calculate the level of the CT slice and as the reference for sectioning of the hemimandible.

Dimensional analysis of the parietal bone in areas of surgical interest and relationship between parietal thickness and cephalic index.

Purpose: The aim of this study was to determine the thickness of the parietal bone in bone graft donor sites and to study the relationship between parietal bone thickness and gender or cephalic index.

Materials And Methods: We studied 300 parietal bones from 150 human skulls (84 male and 66 female) from individuals aged 18 to 60 years at the time of death. On each parietal bone, 9 areas were drawn by use of reference anatomic landmarks (bregma, lambda, asterion, and pterion), and bone thickness was determined in the areas adjoining the sagittal suture--superior-anterior (Sa), superior-medial (Sm), and superior-posterior (Sp).

Lateral cortical bone thickness of human mandibles in region of mental foramen.

Purpose: We sought to verify the cortical thickness and presence of tooth roots and inferior alveolar canal where miniplates are placed using the Champy technique to treat parasymphyseal fractures between the canine and premolar. We also studied these anatomic features at the same level anteriorly and posteriorly to the mental foramen.

Materials And Methods: A total of 80 dry, normal adult dentate human hemimandibles (40 male and 40 female) were studied.

Tomographic analysis of the interalveolar space and thickness of the vestibular cortical bone in the parasymphyseal region of adult human mandibles.

Purpose: The aim of this study was to determine by computed tomography (CT) the interalveolar distance on mandible relative to the canine, first and second pre-molar, and the thickness of the cortical bone in the same region.

Methods: A hundred adult cadaveric dentate human hemi-mandibles were examined. A point (P) above the upper margin of the mental foramen was determined, the height at which monocortical screws are inserted to place miniplate according to the technique to treat mandibular fracture.
