Case Report Abstract Cranial defects may result from trauma, disease, and congenital malformations. Repair of cranial defects is indicated to protect underlying brain tissue, provide pain relief at the defect site, improve cosmesis, and minimize patient anxiety. Cranioplasty is accomplished either with osteoplastic reconstruction or restoration with alloplastic implants. Cranial alloplastic imp...

Background: Resection defects of the skull have long been reconstructed using autogenously and alloplastic materials[1]. Complex reconstructions of the orbit have been reported to benefit from patient specific implants [2].Due to new algorithms planning procedures for these implants have recently improved significantly. Rapid production methods such as selective laser melting and rapid prototyp...

BACKGROUND Reconstruction in the head and neck can be difficult owing to the size of the defect or characteristics of the tissue that needs to be replaced. Facial wounds or reconstruction sites can be subject to contamination, thereby risking infection of any implanted material even under ideal circumstances. Particular areas of concern are sites where minimizing the bacterial contamination pri...

Healing of bone defects is the most frequent cause of failure in surgical treatments of an odontogenic ostitic processes. The aim of this study was to determine successfulness in healing of bone defects after implantation of alloplastic co-polymer-polyglycol bone implant. A group of 45 cases with periradicular ostitic processes were examined. The densitometric measurements were taken from radio...

INTRODUCTION Temporomandibular disorders encompass a set of clinical conditions that affect the temporomandibular joint, the masticatory muscles and the associated tissues. Many therapeutic alternatives can be considered, being divided into non-invasive, minimally invasive and invasive interventions. This work aims to report a case of inflammatory joint pain and dysfunction treated with bilater...

Long-term studies have indicated that alloplastic bone grafts composed of nonresorbable hydroxyapatite (NHA) are clinically stable and safe. However, our previous report suggested that NHA grafts may be an etiological factor for recurrent periodontitis in the absence of supportive periodontal treatment (SPT). We removed infected NHA from the root surface by flap surgery in two cases of recurren...

Critical-size osseous defects cannot heal without surgical intervention and can pose a significant challenge to craniofacial reconstruction. Autologous bone grafting is the gold standard for repair but is limited by a donor site morbidity and a potentially inadequate supply of autologous bone. Alternatives to autologous bone grafting include the use of alloplastic and allogenic materials, mesen...

Bone density and quantity are primary conditions for the insertion and stability of dental implants. In cases of a lack of adequate maxillary or mandibulary bone, e.g. in terms of front to back depth or thickness, bone augmentation will be necessary. Lack of bone or bone defects can be caused by inflammation, congenital malformation, trauma or oncological surgery. Several procedures and materia...

Aims Bone defects caused by bone loss due to trauma or tumours are common, with grafting of transplanted tissue currently as the gold standard for bone replacement. However, there are many issues inherent with autograft, including donor site morbidity, supply of tissue and infection [1]. In order to overcome these drawbacks, a diverse array of synthetic biomaterials is under development [2]. Ca...

The objective of this study was to compare the alveolar bone growth in the 2 sides of the maxillary sinus after bilateral sinus lift procedures were performed with the simultaneous placement of dental implants in 20 consecutive patients. After elevation of the Schneiderian membrane, one side had only platelet-rich plasma (PRP) gel applied, while the other had placed only alloplastic graft mater...
