PURPOSE The modified Hughes procedure is used to reconstruct full-thickness lower eyelid defects. A tarsoconjunctival flap from the upper eyelid replaces the posterior lamella, whereas a skin graft, a skin flap, or a skin-muscle flap restores the anterior lamella. The conjunctival pedicle from the upper eyelid is divided after vascularization of the reconstructed lower eyelid is judged to be ad...

statement of problem: recent literatures show that accelerated portland cement (apc) and calcium hydroxide ca (oh) 2 may have the potential to promote the bone regeneration. however, certain clinical studies reveal consistency of ca (oh) 2, as one of the practical drawbacks of the material when used alone. to overcome such inconvenience, the combination of the ca (oh) 2 with a bone replacement ...

BACKGROUND Guided bone regeneration (GBR) using a non-absorbable barrier has provided clinicians the ability to place implants in sites compromised by insufficient bone, including immediate extraction sites. Recent evidence suggests that successful GBR outcomes may be possible using bioabsorbable polymer barriers. METHODS This report presents a case series of 9 patients with 8 fenestration an...

BACKGROUND Reconstruction of soft tissue defects in the lower third of the leg remains challenging. Anatomical constraints limit the local options available for complex defects especially lower third of leg. Local flaps based on perforator vessels are raising interest in reconstructive surgery of the limbs. We present our experience with perforator flaps for reconstruction of soft tissue def...

Guided bone regeneration (GBR) evolved from the concept of guided tissue regeneration (GTR) and has been used for reconstructing sites with bone deficiencies associated with dental implants. For GBR, the use of absorbable collagen membranes has been increasing, but, at present, scientific information on the use of collagen membranes for GBR is limited. This study was aimed to clinically and his...

Purpose: This study aimed to evaluate the changes in damping capacity according striking and bone conditions of implants placed a porcine rib using two devices (Periotest; Medizintechnik AnyCheck; Neobiotech).Materials Methods: In first experiment, 20 implant fixtures were on ribs connected at three healing abutment heights (3.0, 4.0, 5.0 mm). The capacities measured different vertical angles (...

BACKGROUND Decalcified freeze-dried bone allograft (DFDBA) may have the potential to enhance bone formation around dental implants. Our aim in this study was the evaluation and comparison of two types of DFDBA in treatment of dehiscence defects around Euroteknika(®) implants in dogs. METHODS In this prospective clinical trial animal study, all mandibular premolars of three Iranian dogs were e...

Background and Aim: Cone beam computed tomography (CBCT) produces high-quality data in periodontal diagnosis and treatment planning. The aim of this study was to compare the accuracy of CBCT with intraoral digital and conventional radiography in the measurement of periodontal bone defects.  Methods and Materials: In this diagnostic research, two hundred and eighteen artificial osseous d...

background and aims. wound dehiscence after lower third molar surgery extends the postoperative treatment period and may cause long-standing pain. the aim of this study was to compare wound dehiscence after removal of wisdom teeth in the most prevalent mandibular impaction (mesioangular class ib) by two different soft tissue flap designs. materials and methods. partially-erupted mandibular thir...
