简要总结
- Evaluation of dimensional changes in alveolar ridge following immediate implantation compared to delayed implantation
- evaluation of the effect of gap dimensions between socket walls and dental implant in implant stability
详细描述
24 hopeless single root teeth will be selected. The horizontal and vertical measurements will be assessed in 12socket after immediate implantation and filling the gape with DFDBA.
Horizontal dimensions (bucco-lingual) of alveolar ridge will be measured at 1,3 and 7 mm using caliper and CBCT , and vertical ridge dimensions at 8 points:(mid-buccal,mid-lingual,mesial,distal,disto-buccal-mesio-buccal,disto-lingual,mesio-lingual ) will be determined using a periodontal probe from the line connecting the two adjacent CEJs ,and dimensional changes will be measured after 3 months following implant insertion with the same device during the second stage surgery.
The vertical and horizontal dimensions between the implant and alveolar crest and between the crest and base of the gap will be measured at 8 points:(mid-buccal,mid-lingual,mesial,distal,disto-buccal-mesio-buccal,disto-lingual,mesio-lingual ).
The primary and secondary stability will be measured using Osstell at baseline and 3-month later.
Twelve sockets will heal without grafting materials, soft and hard tissue measurements including horizontal and vertical ridge dimensions will be determined. All the measurement will be assessed using caliper and CBCT at the time of extraction and 3-month later at the time of implant insertion.

研究组 & 干预措施
immediate implantation
Immediately after tooth extraction, dental implant is inserted.
干预措施: immediate implantation (Procedure)
Delayed implantation
Four months after extraction, Dental implant is inserted.
干预措施: Delayed implantation (Procedure)
结局指标
主要结局
dimensional changes
时间窗: baseline to 3 months
Horizontal dimensions (bucco-linguall) of alveolar ridge will be measured at 1,3 and 7 mm using caliper and CBCT , and vertical ridge dimensions at 8 points:(mid-buccal,mid-lingual,mesial,distal,disto-buccal-mesio-buccal,disto-lingual,mesio-lingual ) will be determined using a periodontal probe from the line connecting the two adjacent CEJs ,and dimensional changes will be measured after 3 months following implant insertion with the same device during the second stage surgery.
次要结局
- implant stability(baseline to 3 months)
