Abstract
The aim of the present case report was to demonstrate the vertical gain in the posterior resorbed mandible utilizing the use of an Allograft Customized Bone Block. The case presents a 66-year-old healthy female nonsmoker who lost her right mandibular molars long time ago. In the past, she had an implant placement, which failed due to a fracture of the implant. Due to the high risk of mandibular nerve damage, the implant was left in the jaw and was completely covered with bone. Since the jaw was completely atrophic and short implants were not an option, a vertical ridge augmentation was required. This case report presents the use of an Allograft Customized Bone Block as a good option in patients with an atrophic mandible, showing no vertical bone resorption five months after placement and great osseointegration of the placed implants.
Highlights
Patients with a highly resorbed atrophic mandible who require implants have several treatment options
Short implants usually do not require simultaneous bone grafting, resulting in reduced surgery time and patient morbidity compared to bone grafting and regular implant placement in a one- or two stage approach [1]
When the bone volume is not sufficient for short implant placement, vertical bone augmentation needs to be considered as a serious treatment option
Summary
Patients with a highly resorbed atrophic mandible who require implants have several treatment options. When the bone volume is not sufficient for short implant placement, vertical bone augmentation needs to be considered as a serious treatment option. Virtual planning of the bone block requires advanced knowledge of both anatomical, as well as implant, considerations. This method has been able to show promising results in several case reports over the last couple of years [2,3,4,5,6,7]. Puros® Allograft Customized Bone Blocks (ACBB) have been available since 2014 They are prepared based on the multi-step Tutoplast® tissue sterilization process, which was developed in 1969 [4]. After purification of the donor material and milling in a clean environment, the block was packaged and sterilized with low-dose gamma irradiation [8]
