The aim of the present study was to evaluate the clinical efficacy of platelet-rich fibrin (PRF) in preserving the alveolar ridge following human tooth extraction. A total of 28 patients were divided into two groups: The experimental and control groups (n=14 each). Following tooth extraction, the experimental group was implanted with PRF membrane, whereas the control group was not. The gingival...

  Objective: Alveolar ridge preservation in patients with inadequate bone volume is one treatment option for successful implant placement and can be done by using bone graft materials. On the other hand, Ceno Bone has been recently produced by Hamanand Saz Baft Kish Co. as a bone bioimplant of allograft origin. This study aimed to assess the clinical, histologic and histomorphometric results of...

OBJECTIVES To evaluate the performance and safety of placing a collagenated xenogeneic bone block (CXBB) graft for the lateral bone augmentation of the alveolar crest prior to implant placement. MATERIAL & METHODS In patients with single or multiple tooth gaps and a severe horizontal collapse of the alveolar ridge, a ridge augmentation procedure was performed using CXBB fixated with osteosynt...

Previous physiological studies suggest that increased lung growth in patients with acromegaly is associated with either a normal or above normal pulmonary transfer factor. These findings can be interpreted to suggest either alveolar hypertrophy or hyperplasia as the mechanism for lung growth in this condition. Since the ventilated airspaces retain normal elastic properties, we wanted to determi...

Objectives: An efficient, safe, affordable and easily accessible measuring instrument for quantitative assessment of bone prior to dental implant placement enables more accurate treatment planning. Costly imaging modalities are neither widely available, nor affordable for some patients. This study sought to assess the efficacy of a newly designed digital bone gauge for measurement of bone width...

BACKGROUND The effect of membrane exposure on guided bone regeneration (GBR) for lateral ridge augmentation has been poorly addressed. This case-controlled study aimed to investigate potential effect of membrane exposure lateral ridge augmentation and subsequent implant placement. METHODS A total of 14 patients that did receive lateral ridge augmentation procedure using allogeneic cancellous ...

Guided bone regeneration has been applied in implant dentistry for increasing the width and height of the alveolar ridge in areas with insufficient bone. Various materials and techniques have been used for this purpose. It refers to a surgical procedure by which utilizing a mechanical barrier to create a secluded space around the defect to permit bone regeneration without the competition of oth...

A tandem-loop nickel titanium temperature-activated palatal expansion appliance was developed that produces light, continuous pressure on the midpalatal suture and requires little patient cooperation or laboratory work. The purpose of this study was to compare the effectiveness of the nickel titanium palatal expansion appliance with that of a rapid palatal expansion appliance. The study sample ...

It is very difficult to determine the time point of inserting implants for diabetic patients. And less we know about how diabetic sockets change with time. Based on the previous studies on non-diabetic socket healing, we analysed preand post-extraction cone beam computed tomography images of type 2 diabetes patients (n=93) and, age and sex matched non-diabetic controls (n=93) to investigate pos...
