Does Piezosurgery Decrease Patient Morbidity in Surgically Assisted Rapid Palatal Expansion Compared With Saw and Burrs?

Purpose: The present study compared the postoperative pain, edema, patient satisfaction, and operating time with the use of piezosurgery, a reciprocal microsaw, and conventional burrs in the surgically assisted rapid palatal expansion (SARPE) technique for the correction of transversal maxillary deficiency. The results of the present study may help clinicians minimize the postoperative complaints of patients after SARPE.

Patients And Methods: The present randomized single-blind study included patients who had undergone SARPE with piezosurgery, a reciprocating microsaw, or conventional burrs.

Does the topical use of epinephrine for sinus floor augmentation affect systemic hemodynamics?

Purpose: Although epinephrine is one of the most commonly used vasoconstrictor in association with local anesthesia in dentistry, systemic effects of topical admission of epinephrine for sinus augmentation have not been investigated yet. The purpose of this study was to reveal the safety of epinephrine as a topical vasoconstrictor in sinus augmentation procedures.

Patients And Methods: Forty-three healthy patients who require sinus floor augmentation for dental implant placement were included in this study.

Effects of different fixture geometries on the stress distribution in mandibular peri-implant structures: a 3-dimensional finite element analysis.

Objective: The purpose of this study was to compare 3 different solid screw implant fixture designs of stepped cylindric tapered, straight cylindric nontapered, and cylindric with vertical groove tapered on stress distribution in the posterior mandible at a fixed interimplant distance of 1.0 cm.

Study Design: Three-dimensional finite element analysis was used to compare stress distribution around the endosseous titanium implants using 3 different implant fixture geometries.

Informed consent: what do patients really want to know?

Purpose: Although it is generally advised to provide patients with as much information as possible during the informed consent process, little is known about the amount and type of information that patients actually desire. The purpose of this study was to address this question.

Patients And Methods: We gave 212 patients (93 men and 119 women) presenting to an emergency clinic for oral surgery, ranging in age from 18 years to more than 50 years, a questionnaire containing 12 questions at their initial visit that asked them how much information they would like about the general and specific risks associated with the procedure.

Bone lid technique with piezosurgery to preserve inferior alveolar nerve.

The inferior alveolar nerve is at risk during surgical removal of impacted mandibular teeth and excision of benign tumors of mandible. Manual and/or mechanical instruments used in the close proximity of delicate structures do not allow the control of the cutting depth and can damage these structures by accidental contact. Piezoelectric surgery is a new and innovative bone surgery technique using the microvibrations of special scalpels at ultrasonic frequency so therefore soft tissue will not be damaged even upon accidental contact with the cutting tip.
