Clinical Evaluation of NiTiDent Tuah Porous NiTi Dental Implants

A Prospective, Open Label, Randomized, Double Arm, Multicenter Study to Evaluate the Performance of NiTiDent Tuah Porous NiTi Dental Implants in Single Tooth Gap in the Posterior Mandible

The purpose of this prospective, open-label, randomized, double arm multicenter study is to evaluate the safety and clinical performance of a newly developed NiTiDent Tuah porous NiTi dental implant (from Nitium Technology Sdn Bhd) in singletooth gap in the posterior mandible 1 year after implant placement and 8 months after implant loading. Second, To investigate the clinical outcome of the interventional dental implant (NiTiDent Tuah Porous NiTi dental implant) compared to control dental implant. The hypothesis is set to no difference in the clinical outcome for the two types of implants based on the outcomes of the primary and secondary endpoints.

The primary endpoint is to assess implant survival rate over a 12-month period. A surviving implant is defined as an integrated implant in the patient's jaw bone at the time of assessment. Secondary endpoints include the assessment of implant stability, crestal bone levels, peri-implant soft tissue conditions, implant success, and patient satisfaction and related outcomes over several intervals within a 12-month period.

Inclusion Criteria:

1. Patients of either sex and at least 18 years of age.
2. Ability to understand and provide informed consent before starting the study.
3. Ability and willingness to comply with all study requirements to be evaluated for each study visit.
4. The patient, if of child-bearing potential, has a negative urine pregnancy test.
5. Adequate oral hygiene to allow for implant therapy consistent with standards of care.
6. Adequate bone volume to accommodate the planned endosseous dental implant placement of 4.5 mm in diameter and 10 mm in length.
7. Adequate interocclusal distance (crown height space) of at least 6 mm measured from the alveolar crest to the occlusal table.
8. Intact buccal table as verified by Cone Beam Computed Tomography (CBCT). If absent, patient should be excluded from enrollment in the study.
9. One tooth in the posterior mandible (first or second molar) planned to be restored with a dental implant as determined by the patient's dental provider.
10. The site to be treated is surrounded by two natural teeth (one anterior and one posterior to it).
11. Primary stability of implant consistent with standards of care is achieved at the time of implant placement. Minimum primary stability, insertion torque at the value stated in the implants's Instructions for Use (IFU) (this will be a criterion that is met at the time of surgery).
12. Patients must be physically able to tolerate conventional surgical and restorative procedures.
13. Presence of opposing dentition with a functional occlusion.

Exclusion Criteria:

1. Presurgical

   • Severe wear with an etiology of bruxism or clenching habits.
   • Patients in need of bone grafting at the site of the intended implantation site.
   • Patients who have previously failed implants at the site intended for study implant placement.
   • Patients in need of other treatments or surgeries at a site adjacent to the intended implantation site.

   • Use of any investigational drug or device within the 30-day period immediately prior to implant surgery.
   • Patient is pregnant and lactating.

2. Post Implant Surgery:

   • Lack of implant primary stability.
   • Inappropriate implant position for prosthetic requirements.
   • Major simultaneous augmentation procedures at surgery.
   • X-ray not showing the implant from first bone contact to apical tip.
