      <study_design>Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: The sampling method is random among the people referring to the maxillofacial surgery department of Tabriz Dental School. The randomization method is simple and the unit is individual. Our tool for randomization is the randomized number chart. Furthermore, the allocation of treatment to patients will be done Randomly. To do this, the types of treatment are identified with code A (with the laser) and B (without laser) then will be placed in sealed envelopes and will be stirred. Then they are randomly taken out of the bag and after observing the code, the treatment will be given to the patient. None of the patients will be informed about another patient's treatment, Blinding description: Blinding should be done in the evaluation phase of bone resorption, which will be done by coding the studied groups. In such a way the evaluator can not diagnose the type of treatment with and without laser before evaluation.</study_design>

      <i_freetext>Intervention 1: Intervention group: Immediately after tooth extraction, the implant is placed in the socket area of the tooth according to the standard protocol. Low-power 660 nm diode laser treatment is started immediately after surgery and repeated three times a week for two weeks. The amount of bone at the implant site is measured by periapical intraoral radiography and by computer software immediately after surgery and four months later. Intervention 2: Control group:  Immediately after tooth extraction, the implant is placed in the socket area of the tooth according to the standard protocol. Treatment by laser doesn't use. The amount of bone at the implant site is measured by periapical intraoral radiography and by computer software immediately after surgery and four months later.</i_freetext>
