Brief Summary
This study is mainly targeted affected teeth which could not be retained, and patients are willing to undergo implant repair at the later stage. After teeth extraction, Geistlich Bio-Oss ® Particles or Bio-Oss ® Collagen are immediately implanted in the teeth extraction socket and covered with Bio-Gide ® collagen membrane for site preservation.Through postoperative follow-up, postoperative clinical and imaging objective indicators, combined with the subjective evaluation of surgeons and patients, and compared with conventional extraction treatment method, the study is aimed to evaluate the effectiveness of different site preservation of alveolar crest preservation, in order to reduce the alveolar bone width and height loss, effectively reduce alveolar bone absorption, or even achieve bone incrementation, thus to get the ideal site preservation effect, to improve the oral implant success rate, improve implant aesthetic score and patient satisfaction, provide more clinical standard reference of the clinical application of site preservation.

Conditions
Outcome Measures
Primary Outcomes (2)
Changes in the alveolar crest height - central
The central alveolar bone height of the ideal implant site will be measured with CBCT at 3 months after tooth extraction or plus site preservation
up to 12 weeks after Dental extraction or site preservation surgery
Changes in the alveolar crest width - central
The central alveolar bone width of the ideal implant site will be measured with CBCT at 3 months after tooth extraction alone or plus site preservation
up to 12 weeks after Dental extraction or site preservation surgery
Secondary Outcomes (8)
Changes in the alveolar bone width - different depths
up to 12 weeks after Dental extraction or site preservation surgery
Changes in the alveolar bone height - different horizontal sites
up to 12 weeks after Dental extraction or site preservation surgery
Soft tissue thickness
up to 12 weeks after Dental extraction or site preservation surgery
Plaque index (PLI)
up to 12 weeks after Dental extraction or site preservation surgery
Bleeding index (BI)
up to 12 weeks after Dental extraction or site preservation surgery
- +3 more secondary outcomes
Study Arms (3)
Geistlich Bio-Oss ® Particles + Bio-Gide ® collagen membrane
The first group of patients selected for site preservation will be performed with Bio-Oss ® Particles + Bio-Gide ® collagen membrane after tooth extraction
Geistlich Bio-Oss ® Collagen + Bio-Gide ® collagen membrane
The second group of patients selected for site preservation will be performed with Bio-Oss ® Collagen + Bio-Gide ® collagen membrane after tooth extraction
Conventional healing after tooth extraction, without site preservation
The third group of patients selected will be performed without site preservation after tooth extraction, and only conventional healing
Eligibility Criteria

- patients willing to performed no site preservation after tooth extraction and only conventional healing.
You may not qualify if:
- patients unwilling to sign the informed consent form and the letter of authorization;
- patients has a potential systematic diseases;
- patients had previously been treated with radiation therapy;
- patients can not re-visit on time.
