Detailed Description
This clinical investigation is a prospective, multi-centre study to evaluate bone gain after horizontal augmentation using creos xenogain bone graft substitute.
Patients included in the study are in need of a GBR procedure prior to implant placement in the premolar and posterior region of the mandible.
Primary endpoint include the bone gain after 8 months healing period, while secondary endpoints includes histological analysis 8 months after performance of the augmentation procedure as well as Implant survival, implant success and marginal bone levels evaluated over a period of 1 year after definitive prosthetic delivery.

Description
Inclusion Criteria:
- Subjects between 18 and 80 years old.
- Patient has signed informed consent to participate in the study.
- Patients in need of horizontal ridge augmentation prior to implant placement in the premolar and posterior region of the mandible
- Horizontal defect classified as: Horizontal medium defect (Hm) (4-6 mm defect) or Horizontal large defect (Hl) (≥7 mm defect)
- Patients presented with a combination defect Horizontal/Vertical with a maximum of 2mm loss of vertical dimensions (minimal vertical dimension for patient inclusion is 7.5 mm defined as the distance from the anatomical landmark, alveolar nerve or lingual dehiscence)
- The subject must be in good physical and mental condition
- The subject is willing and able to comply with all study related procedures (such as exercising oral hygiene and attending all follow-up procedures).
- Full-mouth bleeding score (FMBS) lower than 25%.
- Full-mouth plaque score (FMPI) lower than 25%.
- The subject is suitable for a 2-stage surgical procedure
Exclusion Criteria:
- Severe bone defect classified as: Vertical medium (Vm) (4-6 mm defect) or Vertical large, (Vl) (≥7 mm)
- Medium (Cm) and Large (Cl) classified combination defects Prior bone augmentation in the area planned for treatment (i.e ridge preservation)
- Health conditions, which do not permit the surgical (including anesthesia) or restorative procedure.
- Any disorders directly in the planned implant area such as previous tumors, chronic bone disease.
- Any ongoing application of interfering medication (steroid therapy, bisphosphonate, etc).
- Alcohol or drug abuse as noted in subject records or in subject history.
- Reason to believe that the treatment might have a negative effect on the subject's overall situation (psychiatric problems), as noted in subject records or history.
- Heavy smoking (> 10 cigarettes per day).
- Uncontrolled diabetes, i.e. a subject with diagnosed diabetes that has a history of neglecting doctor's recommendations regarding treatment, food and alcohol intake or A1c level above 8%.
- Poor compliance.
- Active periodontal disease involving the residual dentition.
- Mucosal diseases in the areas to be treated.
- Pregnant or lactating women at the time of bone augmentation procedure.

|
6 months and 1 year after definitive prosthetic delivery
|
Implant success
Time Frame: 6 months and 1 year after definitive prosthetic delivery
|
To demonstrate cumulative success rate of the implants placed in the augmented bone at 6 months and 1 year after definitive prosthetic delivery.
|
6 months and 1 year after definitive prosthetic delivery
|
Marginal bone levels
Time Frame: 6 months and 1 year after definitive prosthetic delivery
|
To demonstrate the changes in marginal bone levels (ΔMBL) around the implants placed in the augmented bone as measured and evaluated by periapical films, 6 months and 1 year after definitive prosthetic delivery
|

|
Histological analysis prior to implant insertion including percentage of vital bone, residual graft and connective tissue or other non bone components
Time Frame: 8 months
|
