Adhesive Dental Clinical Trial
Official title:
A Prospective Human Clinical Study to Assess Primary Stability and Change in Stability by Resonance Frequency Analysis of Immediately Inserted and Restored Dental Implants Using pH-Modified Tetranite® Implant Stabilization Material
The aim of this Pilot Study is to demonstrate the safety and efficacy of the use of Tetranite Implant Stabilization Material (TN-ISM) in delivering enhanced stability to immediately restored dental implants inserted into fresh extraction sockets, with both clinical and patient-related successful outcomes.

Eligibility | Inclusion Criteria: - Subjects must have voluntarily signed the informed consent form before any study related procedures; - Subjects must be males or females who are a minimum of 20 years of age; - Subjects who require a single anterior maxillary tooth extraction and desire a replacement with a dental implant and immediate temporary crown. Candidate subjects may require more than one extraction, and all sitesbut only one site will be considered for inclusion in the study; - Subjects must have opposing dentition (natural teeth, fixed or removable restorations); - Subjects must be committed to the study and the required follow-up visits; - Subjects must be American Society of Anesthesiology Grade (ASA) I or ASA II; - Subjects who present with a sound bony housing with a visible buccal plate evident at the crest and fenestrations limited to <5.0mm diameter on a cone beam CT; - Subjects who present with a sound bony housing with a visible buccal plate evident at the crest and dehiscences limited to <3.0mm in any direction on a cone beam CT; - There must be sufficient bone height crestal to critical anatomical structures, i.e., the piriform foramen, and maxillary sinus, to safely place a dental implant within the bone contours. Extraction sockets should be able to accommodate an implant =9.0mm in length; - Anatomical conditions must be present to allow an implant crown restoration to be placed at the candidate site, e.g., sufficient interocclusal space, incisal Class1 or Class 2 Div 1 relation, appropriate angulation of the ridge, etc. Exclusion Criteria: - There is at least 2mm of apical bone below the apex of the extraction socket for positive seating of the implant; - Any implant site in which placement of the selected implant leaves an (Horizontal Dimension of Defect) HDD > 2mm in the buccal direction between the implant surface and the labial plate at the most coronal aspect of the extraction socket. |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Implant Stabilization by Resonance Frequency Analysis | The primary endpoint is sufficient bone-to-implant interfacial stiffness post-placement of the implant stabilized by TN-ISM, whereby, sufficient bone-to-implant interfacial stiffness is measured by Resonance Frequency Analysis (RFA) expressed as mean Implant Stability Quotient (ISQ) at 12 months post TN-ISM device and implant placement. For the study to be considered successful, the lower bound of the one-sided 97.5% confidence interval for the mean ISQ should exceed the clinical threshold of 60. | 12 months | |
Secondary | Implant Stabilization by Resonance Frequency Analysis | Sufficient bone-to-implant interfacial stiffness measured by Resonance Frequency Analysis (RFA) expressed as Implant Stability Quotient (ISQ) at 15 minutes, 3 months, and 7 months post TN-ISM device and implant placement. For each timepoint to be considered successful, the lower bound of the one-sided 97.5% confidence interval for the mean ISQ should exceed the clinical threshold of 60; | 15 minutes, 3 months, and 7 months | |
Secondary | Device Related Adverse Events | Low incidence, severity and duration of device-related adverse events throughout the 12 months post TN-ISM device and implant placement follow-up period | 12 months | |
Secondary | Implant Stabilization by Manual Palpation | Immediate implant stabilization demonstrated by lack of clinical mobility of the implant subjected to manual palpation in any direction at 15 minutes after application of the TN-ISM and at 1 month, 3 months and 7 months post TN-ISM device and implant placement; | 15 minutes, 1 month, 3 months, and 7 months | |
Secondary | Implant Success (Composite Measure) | Composite measure of implant success (after criteria of Buser1) at 12 months post TN-ISM device and implant placement consisting of: Presence of the implant at its site of implantation; and, Absence of a recurrent peri-implant infection with suppuration; and, No perceptible mobility upon palpation; Absence of encapsulation, defined as continuous radiolucency around the implant in a periapical radiograph |
12 months | |
Secondary | Volume Loss | Crestal bone level maintenance assessed by analysis of two-dimensional periapical radiographic records showing no more than a 1.0mm loss of height throughout the 12 months post TN-ISM device and implant placement follow-up period | 12 months | |
Secondary | Per-implant tissue health | Peri-implant tissue health demonstrated by direct measurement around the implant at 12 months post TN-ISM device and implant placement follow-up period as compared to existing conditions in the oral cavity near adjacent teeth to the implant site and to baseline around the implant at 3 months post placement | 12 months | |
Secondary | Patient Satisfaction | Subject satisfaction using the patient-reported outcome measures | 12 months |
