To investigate the effect of CoQ10 in soft tissue healing and bone regeneration after extraction in diabetic patients seeking dental implants. Methods: This study will be a randomized controlled clinical trial, 18 patients will be divided equally into three groups. In-vitro studies will be performed to investigate the release of CoQ10 from collagen, swelling ratio, and evaluation of gelation behavior. The patients will undergo tooth extraction and filling of the socket with either collagen or CoQ10/collagen. Empty sockets will serve as a negative control. The bone regeneration of the socket will be determined by radiography, histology, histomorphometry, and polymerase chain reaction (PCR) for bone markers.

| Measure | Description | Time Frame |
|---|---|---|
| Soft tissue healing | Landry index will be used to evaluate the parameters of tissue colour, bleeding response to palpation, presence of granulation tissue, characteristics of the incision margins, and the presence of suppuration. This index assesses wound healing using scores from 1 to 5: a wound with very poor healing receives a score of 1, whereas excellent healing receives a score of 5. | at 1 week |
| change in bone formation | Conebeam computed tomography (CBCT) will be taken at 3 different timepoints; immediatly after extraction to measure height and width of alveolar bone, before implant placement to place implant in accurate position and to compare it with first one to measure the changes in bone height and width and finally at loading to evaluate marginal bone loss. | at baseline, 3 months and 6 months |
| Change in implant stability | Osstell instrument (Integration Diagnostics, Goteborg, Sweden) with Smartpeg™ (Integration Diagnostics, Goteborg, Sweden), a transducer suitable for implants will be used to assess stability of implants by RFA. ISQ (implant stability quotient) will be obtained from the measurement results. During measurement, the Smartpeg™ will be placed over the location of implant prosthesis and the Osstell probe will be approximated to it from the buccal, palatal, mesial and distal aspects of the implant giving four ISQ values. A mean ISQ for each implant is then calculated by averaging the four values. implant stability quotient or ISQ score in a range of 0-100. | at baseline and 3 months |
