The concept of overbuilding the implant site in the esthetic zone is paramount in creating the inconspicuous implant restoration. If teeth are congenitally missing, the site may be underdeveloped. Tooth extraction and trauma may lead to ridge deformities. The goal is to create an enhanced site for the restorative clinician. This site can then be molded to an ideal gingival framework. Cases are ...

Tooth extraction is usually followed by bone reduction. In the maxillary posterior region, this remodelling combined with sinus pneumatisation and periodontal defects may lead to a reduced basal bone height available for implant placement. Sinus floor elevation can be performed with different surgical techniques. Crestal approach has demonstrated to be effective, less invasive, and associated w...

Surgical correction of hallux limitus or degenerative articular disease of the first metatarsophalangeal joint (MPJ), whether as singular conditions or in the face of concomitant hallux abducto valgus, is a dilemma with which foot surgeons have struggled with for almost a century. The ideal procedure would provide adequate pain-free motion of the first MPJ without shortening the hallux or unwei...

After reading this article, the reader should be able to: • describe requirements that would lead to success with immediate implant placement and loading. • describe important surgical considerations to increase the survival of immediate implant restoration. • discuss advantages in the single appointment fabrication of computer-assisted designed and machined porcelain for implant restoration. •...

With the introduction of in-office cone beam computed tomography (CT), improved access to conventional CT scanning, and dental implant treatment planning software allowing on-thespot 3-dimensional evaluations of potential implant sites, the use of "flapless" implant surgery has gained popularity among surgeons. Although the flapless approach was initially suggested for and embraced by novice im...

Forty-three sites in 16 patients were selected for placement of implants using osteotomes in a single-stage surgical technique. Most sites were treated to enhance bone quality. Sixteen sites in the posterior maxilla had sinus elevation performed in conjunction with implant placement. No soft tissue coverage of the implant cover screw was attempted in either the sinus-elevated or the nonelevated...

This paper describes orthopedic surgical planning based on the integration of RE and RP. Using symmetrical characteristics of the human body, CAD data of the original bone without damages for the injured extent are generated from a mirror transformation of undamaged bone data for the uninjured extent. The physical model before the injury is manufactured from RP apparatus. Surgical planning, suc...

Dental implants were initiated in 1922 by Branemark, who and associates described the relationship between titanium implant and bone which termed osteointegration, defined as the direct structural and functional connection between living bone and the surface of an implant (Albrektsson et al., 1981). Immediate implant placement, defined as the placement of dental implant immediately into fresh e...

The use of dental implants has increased substantially over the past decade, as have the number of implant-related complications. One of the contributing factors is inadequate training in the prevention, recognition, and treatment of complications. Comprehensive training on implant surgical procedures that includes patient selection, risk management, and complications allows dentists to incorpo...
