“…In the literature, the sandwich osteotomy technique has become more popular in recent years among surgeons due to the low incidence of graft exposure, lack of complications and the easy nutrition of the graft and has been reported as a viableand predictable procedure with a high success rate and improved hard and soft tissue healing [30][31][32][33][34][35][36].…”

Purpose: Dental implant installation in the posterior maxilla depends fundamentally on the presence of an adequate bone quantity. Tooth loss in the posterior maxilla is followed by extensive loss of the alveolar ridge and increased maxillary sinus pneumatization that often makes implant installation difficult to achieve. Maxillary sinus floor augmentation is traditionally the common surgical technique to overcome this situation. When the deficiency in the vertical dimension relates more to severe ridge resorption, crestal ridge augmentation should also be considered. Posterior maxillary sandwich osteotomy combined with sinus augmentation, using inter–positional bone graft might be a viable option to address this problem. This study describes a successful implementation of this technique to solve a severe vertical osseous ridge defect under the sinus floor. Material and Methods: A two–stage lateral wall sinus floor augmentation combined with inter–positional sandwich osteotomy followed by the insertion of dental implants with adequate length and diameter was performed. Deproteinized natural bovine bone mineral (DBBM) covered by a resorbable collagen membrane were used. Rehabilitation of this area was completed by a standard prosthetic protocol. Results: As a result of completing the above procedure favourable bone mass and form was created to enable implant placement in positions that are optimal from a prosthetic and esthetic point of view in terms of reshaping the alveolar crest and normali- zing the interocclusal distance improving the crown–implant ratio. Conclusion: This case demonstrates a step–by–step illustration of an innovative technique for overcoming a vertical ridge defect combined with increased maxillary sinus pneumatization. It can be concluded that this novel technique is recommended to meet the dimensional requirements of bone augmentation both crestal and intrasinusal in severe atrophic posterior maxilla to achieve an improved alveolar plane, equalized crown–to–implant ratios, and a more favourable gingival shape.

“…The variations of this surgical technique have been described by several authors [15,[22][23][24][30][31][32][33][34][35][36]. The main advantages of this technique are the potential for three-dimensional reconstruction, providing a more stable alveolar crest with long-term outcome, and minimal morbidity [37,38].…”

“…However, we believe that the results of this study have implications and consequences for every technique and situation when an insert touches deep cortical bone in the absence of or with low/insufficient irrigation. Deep osteotomies involving cortical walls in the absence of direct irrigation can occur not only accidentally during implant site preparation but also intentionally during other surgical procedures, such as the onlay sandwich osteotomy technique or the extraction of impacted wisdom teeth …”

Objective: Facial asymmetry is one of common complaints in plastic and craniofacial surgery in Orient. Hemimandibular dysplasia has considered to be the key role in facial asymmetry. Despite of the undergrow of mandibular length and height, the lackness of mandibular thickness contributes to the asymmetry. The aim of this study was to describe the therapeutic efficiency of mandibular augmentation with a new sandwich osteotomy with interpositional natural coral and coralline hydroxyapatite (CHA). Methods: Nine goats were randomly divided into 3 groups and observed at 6, 12, and 18 months after surgery. All goats received splitting of bilateral mandibular outer cortex and interpositional grafting with natural coral and CHA, respectively (sandwich osteotomy). Data were evaluated and statistically analyzed by t-test. Results: All goats were observed at 3 different time points. The computed tomography images show that the area of operation was healed and the thickness of the mandible was increased in 3 time points. In the 3 groups, mandibular thickness and volume were significantly different compared with those before operation (P < 0.05). The volume of CHA group improved better than coral group (P < 0.05). Conclusion: This study provides a promising alternative method for mandibular augmentation with a sandwich osteotomy and interpositional grafting with natural coral and CHA. The thickness and volume of mandible had been effectively increased in follow-ups.

Effect of Alveolar Segmental Sandwich Osteotomy on Alveolar Height: A Preliminary Study

Abstract: Sandwich osteotomy can be used as an alternative technique to increase alveolar bone height prior to implant placement. Moderate alveolar deficiency can be predictably corrected by this technique.
