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.

Buccal injection of articaine to anesthetize the palatal mucosa.

Buccal and palatal injections are required for administration of anesthetic agents before maxillary tooth extractions, but palatal injections are painful for patients. Studies suggest that the palatal injection can be eliminated when articaine is delivered as a local anesthetic agent via buccal injection, but the anatomical mechanism for this effectiveness remains unclear. The objective of this study was to explore the potential mechanism by which buccal infiltration results in palatal anesthesia.

In-vitro comparison of different palatal sites for orthodontic miniscrew insertion: Effect of bone quality and quantity on primary stability.

Introduction: This experiment was undertaken to assess the primary stability of orthodontic miniscrews inserted at different sites in human cadaveric palatal bone for temporary skeletal anchorage, and to determine the effect of bone quality and quantity on their primary stability using microcomputed tomography imaging.

Methods: A total of 10 cadaveric maxillary hard palates were used for insertion of 130 orthodontic miniscrews (VectorTAS; Ormco, Orange, Calif; length, 6 mm; diameter, 1.4 mm).

A Three-dimensional Analysis of Zygomatic Symmetry in Normal, Uninjured Faces.

Current approaches to facial reconstruction are based on the assumption of facial symmetry, though this has yet to be established in the literature. Through quantitative and qualitative analysis, symmetry of normal, male faces is examined here using the zygomatic complex as a bellwether for the rest of the facial skeleton. Three-dimensional models reconstructed from the computed tomography scans of 30 adult male patients displaying normal facial skeletal anatomy were analyzed.

ANATOMICAL VARIATIONS OF THE GREATER PALATINE NERVE IN THE GREATER PALATINE CANAL.

The greater palatine nerve and the greater palatine canal are common sites for maxillary anesthesia during dental and maxillo-facial procedures. The greater palatine nerve is thought to course as a single trunk through the greater palatine canal, branching after its exit from the greater palatine foramen. We describe intra-canalicular branching variations of the greater palatine nerve found in 8 of 20 embalmed dissection specimens.

Ultrasound-guided greater palatine nerve block: a case series of anatomical descriptions and clinical evaluations.

Background: Greater palatine nerve (GPN) block is commonly performed for maxillary and palatal anesthesia by using bony landmarks. Ultrasound (US) can be used to consistently identify greater palatine foramen (GPF) as a defect in the bony palate enabling US-guided injections near the foramen.

Methods: We scanned and injected 16 undissected well-embalmed hemisectioned cadaveric heads after excluding major anatomical malformations.

Determining position of the inferior alveolar nerve via anatomical dissection and micro-computed tomography in preparation for dental implants.

Background: The inferior alveolar nerve courses anteriorly within the mandibular canal, providing sensory nerve supply to the mandibular teeth, the buccal mucosa, the gingiva, and the soft tissues of the lower lip and chin. To avoid damage to this nerve and resulting sensory disturbances, its exact location must be known before placement of a dental implant. Imaging modalities currently used to visualize the position of the inferior alveolar nerve may be inaccurate.
