Brief summary: 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.

Detailed description: 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.

Eligibility criteria: 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

   * Patient reports tobacco uses within the last five years. Tobacco use for this study is defined as a current smoking habit with moderate or heavy smoking (more than 10 cigarettes per day) or tobacco chewing use.
   * History of alcoholism or drug abuse within the past 5 years.
   * 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.
   * Patients with active infection or severe inflammation in the areas intended for implant placement.
   * Patient has significant untreated periodontal disease, severe recession, caries, clinical or radiographic signs of infection within two adjacent tooth positions of implant area.
   * History of HIV infection, Hepatitis B or C.
   * Patients has history of systemic disease that precludes standard dental implant therapy or alters daily activities to a level consistent with ASA (American Society of Anesthesiologists) III classification (including cardiovascular, hepatic, renal, gastrointestinal, metabolic, neurologic, pulmonary, endocrine, autoimmune, or psychiatric disorders).
   * Presence of local inflammation or mucosal diseases such as lichen planus.
   * Patient has history of consistent with high risk for subacute bacterial endocarditis.
   * Current hematological disorder or warfarin (or similar) therapy.
   * Patient has history of disease that affects bone metabolism, congenital connective tissue disorders (e.g., osteogenesis imperfecta), or Paget's disease.
   * Patient is taking medications or having treatments known to have an effect on bone turnover, including thiazide diuretics, calcitonin, systemic steroids, bisphosphonates, vitamin D (\>800 IU/day), estrogen or progesterone therapy.
   * History of steroid treatment of duration of 2 weeks or longer in the past 2 years.
   * Patient currently undergoing chemotherapy.
   * Patient has history of radiation treatment to the head or neck.
   * Physical or mental handicaps that would interfere with patient's ability to exercise good oral hygiene on a regular basis.
   * 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.
