Die zweizeitige Unterkieferrekonstruktion mit einer 2,7-mm-Überbrückungsplatte

Abstract

The two-phase reconstruction of the mandible with a 2.7-mm-Martin-reconstruction-plate creates a tumor free period that is followed by bone grafting to the embedded plate. We have treated 61 patients following this pattern from 2000 to 2005, follow-up was done in 56. 14 patients had received radiotherapy of 70 Gy. 43 plates healed in without any complications. Until 2005 bone grafting had been performed in 18 patients, in ten patients the plate had been removed.

52 Mandibular Reconstruction and Osseointegrated Dental Implants

“…Advantages associated with this flap such as a reliable, lengthy pedicle, excellent soft tissue properties for intraoral reconstruction, and ease of harvest have likely contributed its popularity. 72,73 However, the major limiting factor for OCRFF use in mandibular reconstruction is the quality of and quantity of bone stock. The 10-12 cm of available bone is extremely thin, is often not suitable for anterior mandibular reconstructions, and does not support osseointegrated implant placement.…”

Biomechanical In Vitro Study on the Stability of Patient-Specific CAD/CAM Mandibular Reconstruction Plates: A Comparison Between Selective Laser Melted, Milled, and Hand-Bent Plates

“…7,8 In an increasing number of patients, however, this is not feasible or highly risky due to various concomitant and underlying diseases, so that a solely alloplastic reconstruction, usually using a titanium reconstruction plate, remains the last choice. [9][10][11] Still, problems with purely alloplastic mandibular reconstruction continue to be hardware-associated complications such as plate fractures or loosening of screws. 4,[11][12][13][14][15][16][17][18] An important reason for this seem to be microcracks in the plate, which are produced during contouring with the aid of bending tools.…”
