IRCT20201108049312N1 IRCT 2020-11-29 Ahvaz University of Medical Sciences the effect of window dimension on sinus lift successful rate The effect of window dimension and membrane usage on lateral sinus membrane elevation and soft tissue invasion to sinus cavity 2021-01-01 anticipated 16 Complete https://irct.ir/trial/52164 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Factorial, Purpose: Treatment, Randomization description: Since patients will be candidates for surgery based on referral and it is not possible to access them together at the same time, sampling will be sequential to complete the number of samples. The initial evaluator, if the input criterion is met without knowing the type of surgical technique that will be performed, randomly allocates the patient to a study group using a random number table, Blinding description: It should be noted that the patient and the evaluator (clinical and radiological evaluation) are not aware of the type of window and whether or not to place the membranes. Of course, the patient is fully aware of the surgery and its purpose and the 4 types of techniques that can be performed, but will not know in which group it is located. The initial and final assessor will also be generally unaware of what technique has been applied to each patient. 2 atrophy of maxillary alveolar ridge posteriorly. Intervention 1: Control group: Group 1 : Patients who perform conventional sinus lift (window size 7-8 mm) without membranes. Intervention 2: Intervention group: Group 2: Patients who perform conventional sinus lift with absorbent membranes. Intervention 3: Intervention group: Group 3: Patients Perform small sine lift windows (windows 5-4 mm) without membranes. Intervention 4: Intervention group: Group 4: Patients who perform small sine lift windows with absorbent membranes. Yes - There is a plan to make this available What will be shared: the data is related to the amount of elevation of the sinus membrane and the surrounding bone around the implant in different sizes of the lateral window with or without the use of membranes. When: starting patient surgery at 1 january 2021 till 1march 2021 To whom: open access in public Conditions: There are no special conditions Where to obtain: Send a message to the email of the corresponding author How to obtain: one week Comments:
