Comparison between sandwich bone augmentation and allogenic block graft for vertical ridge augmentation in the posterior mandible.

Introduction: The purpose of this randomized controlled clinical trial was to evaluate 2 different techniques for vertical ridge augmentation (VRA) of the posterior mandible.

Materials And Methods: Sixteen subjects with 19 posterior mandibular edentulous sites requiring VRA were recruited for the study. Sites were randomly treated with either block allograft (BA; N = 9) or sandwich bone augmentation (SBA; N = 10).

Risk of lingual plate perforation during implant placement in the posterior mandible: a human cadaver study.

Aim: To determine the risk of lingual plate perforations using 2 different implants during implant installation in the posterior mandible, so as to avoid a potentially life-threatening situation and/or a compromise of the success of the surgical procedure.

Materials And Methods: Nine human cadaver jaws and 16 edentulous sites with missing mandibular posterior teeth were used. Upon flap reflection, 3.

A decision tree for soft tissue grafting.

Periodontal plastic surgery is commonly performed for esthetic and physiologic reasons, such as alleviating root sensitivity, root caries, and cervical abrasion and facilitating plaque control at the affected site. Currently, there is a lack of information regarding the most appropriate treatment method for the various clinical situations encountered. The aims of this paper are to review and discuss the various clinical situations that require soft tissue grafting and to attempt to provide recommendations for the most predictable technique.

Distance between external cortical bone and mandibular canal for harvesting ramus graft: a human cadaver study.

Background: The aims of this study are to determine the distance of the external surface of the buccal cortical plate to the inferior alveolar canal in the mandibular molar region and to propose a safe thickness for harvesting a mandibular ramus block graft.

Methods: Thirty-four cadavers consisting of 26 dentate jaws and eight jaws in the edentulous molar region were used in this study. All mandibular ramus grafts were harvested by one investigator with the grafts extending from the external oblique ridge (EOR) and 15 mm inferiorly in the apico-coronal direction and extending from the mid-buccal aspect of the first molar to the mid-buccal aspect of the third molar in the mesio-distal direction.
