Dental implants“Tent-Pole” for Reconstruction of Large Alveolar Defects: A Case Report
Section snippets
Report of Case
A 19-year-old woman was seeking a dental prosthesis to replace missing teeth in the right maxilla. The patient underwent surgical removal of a maxillary tumor 1 year 6 months previously. On clinical examination, the right upper first bicuspid, second bicuspid, first molar and second molar were missing, and the edentulous ridge in relation to the sites of the right upper second bicuspid, first molar and second molar was concave. The alveolar ridge in this region of the maxillary bone appeared to
Surgical Planning
The patient was regularly instructed to take amoxicillin 2 g for antibiotic prophylaxis and a preoperative chlorhexidine rinse for 2 minutes. Local infiltration anesthesia was conducted with 2% primacaine with epinephrine.
Discussion
The success of this case indicates that even in a situation with severe tridimensional bone defects, screw tent-pole grafting combined with GBR can serve as an alternative for onlay block grafting. By inserting titanium screws into the grafting site, the intent is to preserve and maintain adequate space under the membrane for bone regeneration and prevent its collapse. By providing mechanical support, it acts as a “screw tent-pole” for the surrounding Bio-Oss graft and prevents soft tissue from

Tentpole technique for bone regeneration in vertically deficient alveolar ridges: A prospective study
2018, Journal of Oral Biology and Craniofacial ResearchCitation Excerpt :The feasibility of screw tentpole technique combined with guided bone regeneration was evaluated in a complicated tridemensional alveolar ridge defect caused by maxillary tumor surgery where regenerated bone was achieved 10 months later, leading to a successful maxillary prosthesis.14 Wang evaluated porous β- TCP combined with autologous osteoblasts to augment edentulous alveolar ridge in a canine model, and demonstrated the potential of porous β-TCP as a substrate for autogenous osteoblasts in bone tissue engineering for alveolar ridge augmentation.15 In this study also, we used titanium screws as “tent pole” which prevented contraction of the soft tissue around the β TCP graft material used in our study.
Clinical outcomes of dental implants after use of tenting for bony augmentation: a systematic review
2017, British Journal of Oral and Maxillofacial SurgeryCitation Excerpt :In this method, titanium screws are used to make the gap. The gap is filled with bony materials, and a membrane is used to prevent the migration of epithelial cells (Fig. 3).35 Four studies reported the outcome after the technique was used, mostly in atrophic maxillary ridges, but also in short-span, partially edentulous ridges.
