Correction of Skeletal Abnormalities in the Totally Edentulous Patient

Correction of Skeletal Abnormalities in the Totally Edentulous Patient After the appropriate clinical and radiographic evaluation, casts should be mounted on an articulator for  determination of the ideal ridge .relationship. The dentist responsible for prosthetic construction should be responsible for determining the final desired position of the maxilla and mandible after surgery. In the case of the total

Segmental Alveolar Surgery in the Partially Edentulous Patient  Supraeruption of teeth and bony segments into an.opposing  edentulous area may decrease interarch space and preclude the construction of an adequate fixed or removableprosthetic« in this area. ‘1Ill’ Ims of teeth in one 0arch may increase till’ difficulty of (JiJtaining a functional and esthetic prosthetic appliance with

Maxillary Vestibuloplasty with Tissue Grafting

Maxillary Vestibuloplasty with Tissue Grafting When insufficient labiovestibular mucosa exists and lip shortening would result from a submucosal vestibuloplasty technique, other vestibular extension techniques must be used. In-such cases a modification of Clark’s vestibuleplasty technique using mucosa pedicled from the upper  lip and sutured at the depth of the maxillary vestibule after a supraperiostc

Submucosal Vestibuloplasty

Submucosal Vestibuloplasty The submucosal vestibuloplasty as described by Obwegeser may be the procedure of choice for correction of soft tissue attachment on or near the crest of the alveolar ridge of the maxilla. This technique is particularly useful when maxillary alveolar ridge resorption has occurred but the residual bony maxilla is adequate for proper denture support. In this technique, underlying submu


SOFT TISSUE SURGERY FOR MAXILLARY RIDGE EXTENSION Maxillary alveolar bone resorption frequently results in  mucosal and muscleattachments that interfere with denture construction, stability, and retention. Because of the large denture-bearing area of the maxilla, adequate denture construction and -stabillty can often be achieved after extensive bone loss. However, excess soft tissue may accompany bony resorpt

Vestibule and Floor-of-Mouth Extension Procedures

Vestibule and Floor-of-Mouth Extension Procedures In addition to the attachment of labial muscles and soft tissues to the denture-bearing area, the mylohyoid and genioglossus muscles in the floor of the mouth present similar problems on the lingual aspect of the mandible. Trauner-” described detaching the mylohyoid muscles from the ‘mylohyoid ridge area and repositioning them inferiorly, effectivel

Transpositional Flap Vetibuloplasty (Lip Switch)

Transpositional Flap Vetibuloplasty (Lip Switch) A lingually based flap vestibuloplasty was ‘first described by Kazanjian.24 In this procedure a mucosal flap pedicled from the alveolar ridge is elevated from ‘the’ underlying an.l sutured to the depth of the .vestibule (Fig. U-‘~~ Till’ inner portion of the lip is allowed to heal by , t:wndal y epithelialization.
