Pneumatization within a maxillary sinus graft: a case report

Abstract

Rehabilitation of edentulous posterior maxilla with implant-supported prostheses frequently presents a challenge to dentists. This is due to insufficient bone within the region, in addition to other limiting factors such as anatomical pneumatization of the maxillary sinus. Thus, grafting of the maxillary sinus is a common procedure used to counteract these problems. Regardless of the type of biomaterial used, the success of the procedure is dependent on the formation of high-quality bone. Therefore, vascularization is a key factor for successful grafting and for the long-term maintenance of the treatment. This paper reports a clinical case of bone graft pneumatization and attempts to elucidate its potential etiology.

Synthesis and characterisation of β-TCP/bioglass/zirconia scaffolds

“…Calcium orthophosphate bioceramics play important roles in the replacement and regeneration of bone tissue due to their chemical composition and similarity to mammalian bones and teeth. The main applications of these bioceramics include healing of bone defects, fracture treatment, total joint replacement, bone augmentation, orthopaedics, craniomaxillofacial reconstruction, spinal surgery, otolaryngology, ophthalmology, and percutaneous devices [1][2][3]. Calcium orthophosphates (CaPO 4 ), such as tricalcium phosphate (TCP), hydroxyapatite, dicalcium phosphate dihydrate, and octacalcium phosphate (OCP), have been used in various shapes, such as coatings, films, layers, and scaffolds, to improve implant biocompatibility and osteoconductivity [4,5].…”

Case report on managing incomplete bone formation after bilateral sinus augmentation using a palatal approach and a dilating balloon technique

“…In this case, the communication was managed by inserting a fibrin sponge, but it resulted in a cyst-like concavity within grafted bone, which was subsequently managed by re-entry and grafting of the affected site prior to implant placement [14]. As seen in this case, incomplete bone formation can be managed with re-entry procedures, but incomplete bone formation often results in unusual sinus floor morphologies that make conventional sinus approaches difficult.…”
