Plain English Summary
Background and study aims
Dental implants are artificial replacements for tooth roots that are placed within the bone of the jaw so that they can be used to support dentures, crowns (caps) or bridges.
In some patients there is not enough bone in their jaw to allow dental implants to be inserted. In cases where a lot of bone is needed, it may be possible to rebuild the jaw using bone taken from another part of the body. DentoGen® is a new bone graft product that can be used in place of bone.
The aim of this study is to evaluate the efficacy of using calcium sulfate bone graft (bone substitute with commercial name DentoGen®).
Who can participate?
Patients aged 25 – 65 years with tooth loss in the anterior area of the maxilla extracted at least 3 months before the study.
What does the study involve?
Patients undergo dental implant surgery as normal using the bone substitute material in place of a usual bone graft. Patients are followed up after four months.
What are the possible benefits and risks of participating?
The possible benefits are to gain bone in the buccal side of the dental implants so that means we could achieve one stage implantation with GBR by a new method using a reliable material allowing us to:
1. Dispense the use of collagen membrane and titanium mesh
2. Reduce the overall treatment plan time in these cases from nearly a year to just 4 months
3. Give the ability to treat the patient with bone loos by dental implant without expose them for more than 1 surgery.
The possible risk is to not having a perfect bone remodelling on the margin of the buccal side of the implant which will slightly effect the aesthetic side of the area

Bone grafting in the buccal side of dental implants when the bone is thin
After local anesthesia a full-thickness flap is made in the implantation site, the best place of the implant in point and axes is determined, a very thin layer of bone is left buccally after socket preparation then the implant is inserted then the graft (CS) is mixed and the buccal bone layer dried by Gauze, after that apply the material on the buccal side by layers and making pressure on it by Gauze moisturizer with the combined solution waiting 2 - 4 minutes until the graft is solid then make sure that the flap can be sutured free of tension to make a firm closure using 4-0 nylon sutures.
Next day a CBCT image is taken of the implantation area, measured to determine the width of the site, the amount of the gain, graft and bone density.
The sutures are removed 8 - 10 days after the surgery.
After 4 months the final CBCT image is taken to do the same measurements and compare it with the previous ones to determine the final width of the site, the amount of the gain, graft and bone density and the resorption rate of the graft.
Primary outcome measure
Using CBCT imaging technique:
1. Width of the bone in the grafted area the day after the procedure and at 4 months
2. Bone and graft density buccally to the implants the day after application and after 4 months
3. Resorption rate of the graft by comparing measures taken the day after and 4 months after
Secondary outcome measures
1. Width in the site of implantation the day after the procedure and at 4 months using CBCT imaging technique
2. The thickness of attached gingiva in the area of implantation before the procedure and 4 months after using CBCT imaging technique
3. The success rate at 4 months (further surgery required, yes or no)
