- Must have read, understood, and signed a consent form
- Must be able and willing to follow study procedures and instructions
- Must have undergone thorough scaling and root planing of the target tooth and be expected to demonstrate good plaque control after instruction in oral hygiene
The target tooth must exhibit the following:
- A pocket depth of 7 mm or greater
- After surgical debridement, 4 mm or greater intrabony defect with at least 1 bony wall
- Sufficient keratinized tissue to allow complete tissue coverage of the defect
- Radiographic base of defect at least 3 mm coronal to the apex of the tooth
Exclusion Criteria:
- Failure to maintain adequate oral hygiene during the screening phase
- Women of child-bearing potential
- A history within the last 6 months of HIV, Type IV heart disease, or end-stage renal disease
- A history of oral cancer or any other cancer (exception: subjects with a history of skin cancers such as squamous and basal carcinoma with end of treatment at least 6 months ago and/or prostate cancer with end of treatment at least 5 years ago may be enrolled)
- A history within 12 months of previous open flap periodontal surgery on the study tooth.
- A diagnosis of pre-malignant oral lesion(s)
- A traumatic occlusion of the target tooth
- Target "study" tooth exhibiting Grade III mobility
- Maxillary molars or maxillary first premolar with a prominent mesial concavity
- Study tooth exhibiting a Class II or greater furcation defect
- Clinical or radiographic signs of untreated acute or chronic periapical infection at the surgical site, apical pathology, root fracture, severe root irregularities, cemental pearls, cervical enamel projections not easily removed by odontoplasty, untreated carious lesions at the cemento-enamel junction (CEJ) or on the root surface, or restorations with open or otherwise defective margins at or below the CEJ
- A history within the last 6 months of the daily use of any tobacco products besides cigarettes (smokeless chewing tobacco, pipe or cigar smoking), or of smoking more than 10 cigarettes per day
- Subjects participating in other clinical trials within 30 days of enrollment
- Subjects having uncontrolled endocrine-induced diseases (e.g. uncontrolled diabetes mellitus and hyperparathyroidism)
- Subjects undergoing current therapy with systemic steroids or other drugs that significantly alter bone metabolism
- Subjects with Localized Juvenile Periodontitis (LJP) sites in the oral cavity

Number of Participants That Met the Success Criteria of Radiographic and Clinical Measurements
Prazo: 6 months post-surgery
|
The primary effectiveness endpoint is a composite endpoint that considers radiographic and clinical measurements at six months post-implantation: the amount of linear bone growth (LBG), which is assessed with the use of radiographs, and the regain from baseline of clinical attachment level (∆CAL), which is assessed clinically.
Linear bone growth (LBG) in a vertical and horizontal direction is determined radiographically at six months post-implantation.
The clinical attachment level (CAL) is the distance from the cemento-enamel junction (CEJ) (or other fixed reference point) generally along the long axis of the tooth to the deepest extent of the periodontal pocket.
The success criteria are ΔCAL ≥1.5 mm and LBG ≥1 mm at 6 months after the treatment.
Both the ∆CAL and LBG must meet the success criteria for a subject to be considered a success.

Change in Clinical Attachment Level at 3 Months
Prazo: Baseline and 3 months post-surgery
|
The clinical attachment level is the distance from the cemento-enamel junction (or other fixed reference point) generally along the long axis of the tooth to the deepest extent of the periodontal pocket.
Change = (3 months measurement - Baseline measurement)
|
Baseline and 3 months post-surgery
|
|
Change in Clinical Attachment Level at 6 Months
Prazo: Baseline and 6 months post-surgery
|
The clinical attachment level is the distance from the cemento-enamel junction (or other fixed reference point) generally along the long axis of the tooth to the deepest extent of the periodontal pocket.
Change = (6 months measurement - Baseline measurement)
|
Baseline and 6 months post-surgery
|
|
Linear Bone Growth at 6 Months
Prazo: Baseline and 6 months post-surgery
|
Linear measurement of bone height in millimeters along mesial and/or distal root surfaces of the defect site is captured radiographically at baseline and 6 months.
Linear Bone Growth = (Baseline measurement - 6 months measurement)
|
Baseline and 6 months post-surgery
|
|
Percent Bone Fill at 6 Months
Prazo: Baseline and 6 months post-surgery
|
Linear measurement of bone height in millimeters along mesial and/or distal root surfaces of the defect site is captured radiographically at baseline and 6 months.
Percent Bone Fill is calculated by dividing Linear Bone Growth at 6 months by bone height at baseline.
|
Baseline and 6 months post-surgery
|
|
Pocket Depth Change at 3 Months
Prazo: Baseline and 3 months post-surgery
|
Length from free gingival margin to the base of the pocket in millimeter is measured with North Carolina 15 mm periodontal probes.
Pocket Depth Change = (3 months measurement - Baseline measurement)
|

|
|
Pocket Depth Change at 6 Months
Prazo: Baseline and 6 months post-surgery
|
