“…However, they have several potential disadvantages, such as requirement for an incision with additional soft-tissue stripping needed for removal, risk of fracture of the screws when removing, radiographic artifacts, allergic reactions, discomfort in oral mucosa, and possible restricted growth of the craniofacial skeleton in pediatric patients. As an alternative, bioresorbable fixation devices for oral and maxillofacial surgery have been well documented [7-9]. …”

“…In a previous study, PLLA-PGA fixation devices were completely resorbed in maxillary and mandibular bone sites without osteolysis from 18 to 24 months after surgery [17]. Such resorbable fixation materials offer many advantages for osteosynthesis over titanium screws in oral maxillofacial surgery, because several of the above-mentioned problems arising from the need to remove the bone fixing screws are eliminated [7-9]. Therefore, we used resorbable PLLA-PGA screws in the present case along with IP-CHA to avoid damage and infection of host bone caused by removal surgery.…”

“…Their study showed that resorbable screws provide excellent graft stability at the graft placement and graft retrieval stages, with no statistically significant difference between the titanium and resorbable groups in regard to the thickness of the mandibular graft site. In a clinical study, Quereshy et al investigated the efficacy of resorbable fixation screws to fix autologous cortical onlay grafts to augment alveolar bone height and/or width in 11 patients [7]. Their results showed that cortical onlay graft integration and survivability were similar between resorbable and titanium screw fixation.…”

“…However, autogenous bone can be affected by mechanical stress and has a risk of infection related to the removal operation. In addition, titanium screw fixation has been shown to produce radiographic artifacts [7-9]. Therefore, resorbable screws are useful alternatives, as no removal is needed.…”

BackgroundOnlay bone grafting techniques have some problems related to the limited volume of autogenous grafted bone and need for surgery to remove bone fixing screws. Here, we report a case of horizontal alveolar ridge atrophy following resection of a maxillary bone cyst, in which autogenous onlay bone grafting with interconnected porous hydroxyapatite ceramics (IP-CHA) and bioresorbable poly-L-lactic/polyglycolic acid (PLLA-PGA) screws was utilized.Case presentationA 51-year-old man had aesthetic complications related to alveolar atrophy following maxillary bone cyst extraction. We performed onlay grafting for aesthetic alveolar bone recovery using IP-CHA to provide adequate horizontal bone volume and PLLA-PGA screws for bone fixing to avoid later damage to host bone during surgical removal. During the operation, an autogenous cortical bone block was collected from the ramus mandibular and fixed to the alveolar ridge with PLLA-PGA screws, then the gap between the bone block and recipient bone was filled with a granular type of IP-CHA. Post-surgery orthopantomograph and CT scan findings showed no abnormal resorption of the grafted bone, and increased radiopacity, which indicated new bone formation in the area implanted with IP-CHA.ConclusionOur results show that IP-CHA and resorbable PLLA-PGA screws are useful materials for autogenous onlay bone grafting.
