      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: The study is performed as a split mouth investigation. The left or right side of each participant would be randomized into either the test group or the control group. Simple randomization will be used to select the type of material at each side. After elevation the sinus membrane, the coin toss method will be used to select the type of material in the right maxillary sinus. Bone+ would be used if the coin lands with heads side up, and OCS-B would be used if the coin lands with tails side up. The left sinus would be augmented with the other material. Only the surgeon and the person performing the randomization are aware of the sample allocation. Patients and individuals performing clinical and histological evaluations would be masked to the grouping information, Blinding description: The principal investigator who performs randomization during surgery and the surgeon are aware of the type of material used. Participants are informed about the process of study and using two types of bone grafting materials; however, they are masked to the grouping information. The surgery would be first performed on the right sinus in each participant.  After preparation of the sinus cavity, the principal investigator would randomly determine the type of substance to be used in the right sinus; the material will be given to the surgeon in such a way that the participant is prevented to get aware of the name of the material. A unique code would be assigned for each patient and sinus by the principal investigator, and all subsequent evaluations will be based on the codes. Postoperative clinical evaluation will be performed by a person who is unaware of the type of material used. Recording of pre- and post-operative radiographic information is done by an oral radiologist who has no knowledge of the type of material used based on the provided codes. The histologic samples are coded by the principal investigator and sent to the oral pathologist who is unaware of the type of grafting material used. Data analysis is also performed by a statistician based on the provided codes.</study_design>
