      <study_design>Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: the selected patients will be divided into two groups by the Balanced block randomization method with a size of 4 blocks. Participants will be randomly allocated (1:1) to group 1 (with bone graft) and group 2 (without bone graft). The randomization sequence will be generated by an independent investigator using computer software ( www.randomization.com ). Balanced Blocked randomization will be used, with a block size of 4. The surgeon will open sequentially numbered, sealed envelopes only after the implants will be inserted at the day of surgeries. Although the surgeon will be aware of the allocated arm, soft tissue dimentional changes outcome assessor will be kept blinded to the allocation, Blinding description: the selected patients are unaware of their assignment to the case group (performing xenograft bone graft) or the control group (not performing xenograft bone grafting).</study_design>

      <i_freetext>Intervention 1: Intervention group: After extracting the specified tooth, the patients received a Dentium brand implant made in South Korea, the gap between the sucket buccal wall and the implant surface will then be filled with US-made SigmaGraft-InterOss xenograft material. After placing the implant, the surgeon takes an impression of the implant, opposing arch impression, and jaw records. on both implant and bone graft, the healing abutment is put. it will be removed 2 weeks after placing the implant, and provisionalization will be replaced. Intervention 2: Control group: After extracting the specified tooth, the patients received a Dentium brand implant made in South Korea, and then the gap between the sucket buccal walll and the surface of the implant will be left empty. After implant placement, the surgeon takes an impression of the implant, opposing arch impression, and jaw records. on the implant, the healing abutment is put. it will be removed 2 weeks after placing the implant, and provisionalization will be replaced.</i_freetext>
