Guided Bone Regeneration of an Atrophic Maxilla Using Heterologous Cortical Lamina

Abstract

Alloplastic dental implants are currently the best way to replace lost teeth. In order to achieve good function and prognosis of dental implants, having bone and soft tissue to support them is necessary. When the amount of bone left is not enough to ensure the outcome of the implant, techniques such as shorts implants, zygomatic implants, or guided bone regeneration have been used. Even though autologous bone is mostly the “gold standard,” other biomaterials such as xenografts have led to the reduction of the morbidity of treatments and to the improvement of the regeneration technique outcomes. We present a clinical case of severe atrophy of the maxilla in which we used different types of biomaterials: heterologous cortical lamina, xenograft and autologous bone, and microscrews.

Multi-Layer Technique (MLT) with Porcine Collagenated Cortical Bone Lamina for Bone Regeneration Procedures and Immediate Post-Extraction Implantation in the Esthetic Area: A Retrospective Case Series with a Mean Follow-Up of 5 Years

“…It can be fixated with pins or osteosynthesis screws [ 13 , 15 , 21 ], or directly sutured (the Fine model) to the surrounding tissues, with a triangular section non-traumatic needle [ 22 ]. These features are particularly helpful when it is necessary to maintain the graft volume in aesthetic areas, as well as in horizontal augmentation [ 15 , 23 , 24 ] of two wall defects, and for covering antrostomy in lateral access sinus augmentation procedures [ 21 , 25 , 26 ]. Lamina can also be used in regeneration procedures with the risk of exposure.…”

Autogenous Tooth Bone Grafts for Repair and Regeneration of Maxillofacial Defects: A Narrative Review

“…Guided bone regeneration (GBR) is a process where new bone formation is guided by the use of a resorbable or non-resorbable membrane [ 72 , 73 ]. In most cases, GBR is performed with or prior to implant placement [ 73 , 74 ].…”

In most cases, GBR is performed with or prior to implant placement [ 73 , 74 ]. Powder-type AUTO-BG material can be placed along with an implant if the osseous defect is larger than 2 mm vertically or horizontally around the implant [ 45 ].…”

Management of Bilateral Mandibular Fused Teeth

“…42 was selected for extraction as 43 had more periodontal support and removal of 42 would provide enough space to correct the malocclusion on the lower arch. Ridge preservation with bone graft (BioOss® from Geistlich®, Wolhusen, Switzerland) [6] and collagen membrane (Osteobiol® from Tecnoss®, Pianezza TO, Italy) [7] were planned to maintain the dimensions of the 42 area while the teeth were being moved.…”
