IRCT20221209056759N1 IRCT 2023-01-08 Sanandaj University of Medical Sciences Clinical comparison of sinus lift via piezosurgery and usual rotary techniques Clinical comparison of sinus lift via piezosurgery and usual rotary techniques especially in terms of the pain after surgery in two sides of a single patient, in people who need bilateral sinus lift and implant in posterior sides of maxilla 2022-11-02 anticipated 22 Complete https://irct.ir/trial/67344 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Crossover, Purpose: Health service research, Other design features: With the exact design of the study in the form of split-mouth crossover, it is tried to eliminate intervening variables that may have confusing results, Randomization description: Block randomization method; It is with quadruple blocks with individual randomization unit. Excel software has also been used for randomization. Concealment has been done in such a way that two independent envelopes are available, one is available to the secretary and the other is available to the surgeon. With each patient's visit, the secretary assigns a row number to the patient based on the order of the visit (after meeting the entry and exit criteria). The surgeon has her own sealed envelope and acts based on it, Blinding description: Before participating in the trial, patients have a complete awareness of reciveing two therapeutic intervention through two surgical methodes; but they do not know that which surgery will be done first and which side (right or left) will get the surgery first. N/A Sinus lift surgery. Intervention group:Augmentin (Amoxicillin + Clavulanic acid) plus Acetaminophen 500 mg, is prescribed for all patients (three times a day or TDS) from one day before surgery until five days after surgery. On the day of surgery, after getting sufficient anesthesia by infiltration and anesthesia of posterior and middle superior alveolar nerves and also greater palatine nerve, patiant is prepared for surgery. 5 minutes before surgery, the patient keeps chlorhexidine mouthwash in his mouth for one minute. The surgical method is performed as a lateral_wall approach sinus lift. A crustal incision is made in the area of ​​the implant along with a vertical freeing incision in the distal of the flap. the mucoperiosteal flap is lifted. After complete reflection of the mucoperiosteal flap, osteotomy is performed in the lateral wall of the sinus using piezosurgery (US_11 LED piezo bone surgery Woodpecker) or rotary at a speed of 2000 rpm.After elevating the sinus membrane, implant is placed at the same time according to the manufacturer's protocol. Also, after evaluating the surgical site, Allogenous frozen-dried corticocancellous bone chips (from Iranian tissue product co. and particle size 1000-2000 micrometers) and absorbable membrane (from Brand Iranian tissue product co., size 20 x 30 mm and thickness 3. to 4. mm) is placed and the area is sutured with four-zero nylon thread.. Yes - There is a plan to make this available What will be shared: information gathered from the patients, is collected in the form of a file called sinus lift study data. All patient information can be provided after de-identification. When: Access will start from the year 1402. To whom: All people who want to access the data are allowed to do so. Conditions: In order to know the information obtained from the patients, they can use the data. The condition of accessing the data requires providing the person's purpose of access and research resume. Where to obtain: Applicants can request access to the data from Fateme Pooladvand. Email address: fatemepooladvand76@gmail.com They can also contact Dr. Ideh Talim Khani. Email address: ideatalimkhani@yahoo.com How to obtain: First, send their desired request. They must comply with the requested conditions and after conducting the necessary checks, this information will be provided to them. Consider the approximate and maximum time of 2 months. Comments:
