简要总结
The purpose of this study is to evaluate CelTx as an alternative to tissue from the palate in the treatment of subjects with Miller Class I or II recession defects who desire root coverage. It is anticipated that this study will demonstrate that CelTx is a safe alternative to palatal tissue and demonstrate potential to enhance oral soft tissue regeneration and wound healing.

入选标准
- •Subject is at least 18 years of age but no more than 70 years of age.
- •Subject has at least two non-adjacent teeth in contralateral quadrants of the same jaw with Miller Class I or II buccal recession (≥ 3 mm) that requires soft tissue grafting. (Teeth may be treated with a maximum difference of 2 mm with respect to depth and width).
- •Females of childbearing potential must have a documented negative urine pregnancy test and must agree to continue acceptable methods of contraception for 6 months post surgery.
- •Subjects must have read, understood and signed an institutional review board (IRB)-approved Informed Consent Form (ICF).
- •Subjects must be able and willing to follow study procedures and instructions.
排除标准
- •Subject has extremely prominent root surfaces (> 1/2 the diameter of the root facial to cortical plate).
- •Subject has interproximal attachment loss beyond the CEJ.
- •Subject with teeth that have a Miller Grade 2 or higher mobility.
- •Subjects with Class V restorations.
- •Subjects with crowns on the teeth selected for treatment.
- •Subjects who have had endodontic therapy in the last 6 months on the teeth selected for treatment.
- •Subjects who have used any tobacco product within the past 3 months.
- •Subjects with only molar teeth suitable for soft tissue grafting.
- •Subject has probing pocket depth >/= 4 mm at either surgical site.
- •Female subjects who are pregnant or lactating.
- •Subjects with any systemic conditions (i.e., uncontrolled diabetes mellitus, cancer, HIV, bone metabolic diseases) that could compromise wound healing and preclude periodontal surgery.
- •Subjects who are currently receiving or have received within two months prior to study entry, systemic corticosteroids, immunosuppressive agents, radiation therapy, and/or chemotherapy which could compromise wound healing and preclude periodontal surgery.
- •Subjects with the presence of acute infectious lesions.
- •Subjects taking intramuscular or intravenous bisphosphonates.
- •Subjects with a known hypersensitivity to bovine collagen and/or iodine (shellfish allergy).
- •Subjects who have received an investigational drug, device or biological/bioactive treatment within 30 days prior to study enrollment (medical or dental).
- •Subjects previously treated with Apligraf/CelTx, Dermagraft or any other cell-based product, including autologous tissue at the target site(s) or immediately adjacent teeth.
- •Subjects, who in the opinion of the investigator, for any reason other than those listed above, will not be able to complete the study per protocol
结局指标
主要结局
Overall Rate of Adverse Events (AEs)
时间窗: 6-month
Adverse events were collected at every visit throughout the 6 month duration. An AE is defined as any adverse change in the subject's medical status when compared with the subject's baseline condition, whether or not the event is related to the study device or a study procedure; or an exacerbation (either in frequency or severity) in a subject's pre-existing condition.
次要结局
- Periodontal Health Measures(6-months)
- Aesthetic Measures(6-months)
- Post-Surgical Subject Comfort Measures(4-weeks)
- Subject Preference Measures(6-months)
