Abstract
ABSTRACTThe high dental implant success rate is directly linked to the presence of adequate bone volume, which enables and maintains the osseointegration of dental implants. This study aimed to report a clinical case of a female with agenesis of the right maxillary lateral incisor (#12), due to cleft lip and palate.Because the bone and mucosal defects of the area, the treatment planning comprised guided bone regeneration with the association of autogenous bone, platelet rich plasm (PRP), and expanded polytetrafluoroethylene membrane (e-PTFE,Gore-Tex), performed in 2005. After nine months, a new evaluation was carried out and revealed that the area was still not suitable for implant placement. Thus, an allogenous bone graft was planned. Elapsed another nine months, the implant was placed. After six months, the implant was reopened and a metal-ceramic crown was installed. The 5-year following-up appointment showed the presence of fistula with purulent secretion at the buccal cortical plate. We attempted to control the fistula with antibiotics and follow-up clinically and radiographically. The examinations suggested a communication with the right nasal cavity, which decreased until nowadays. The osseointegrated dental implant was in function, without symptomatology. The autogenous bone graft is still more effective than allogenous bone graft. Further studies are necessary to achieve better evaluations. KeywordsBone graft; Dental implant; Osseointegration.
Highlights
The high dental implant success rate is directly linked to the presence of adequate bone volume, which enables and maintains the osseointegration of dental implants [1,2]
This study aimed to report a clinical case using bone grafts and dental implant to treat the anterior maxillary tooth agenesis with 10 years of following-up
To the best of the author’s knowledge, the literature claims no difference between particulate and in-block autologous bone grafting regarding the biological aspect, except for the obvious size difference. [12].The advantages of the use of the particulate bone are: the histological partial resorption of the biomaterial, enabling that the natural hydroxyapatite is kept totally inside the bone cavity and mechanical hemostasis [12]
Summary
The high dental implant success rate is directly linked to the presence of adequate bone volume, which enables and maintains the osseointegration of dental implants [1,2]. In the absence of adequate bone volume, one of the most predictable treatments to restore the bone morphology and enable oral rehabilitation is bone grafting [4]. Autogenous bone graft is the gold standard procedure for bone augmentation for the maxillary and mandibular bone [5,6]. This technique is associated with the presence of the donor area and problems, as post-operative pain, risk of paresthesia, limitation in the quality and quantity of the available bone, which may require the use of other bone substitute [7].
