Introduction:

Missing teeth can cause significant discomfort, impacting both function and aesthetics. The loss of a tooth can result from trauma, decay, or even a previous extraction. This case involves a patient who has been missing a lower right back tooth (46) for 2-3 months. The patient also has a medical history of hypertension and diabetes and is currently on medication for both conditions. A comprehensive treatment plan was devised after considering the patient's medical history, clinical examination, and diagnostic tests.

Patient History:

The patient reported a missing lower right back tooth (46) for the past 2-3 months, following an extraction that took place six months ago. The extraction was performed due to a failed restoration or decay in the tooth. The patient has a known history of hypertension and diabetes, both of which are controlled with medication. The patient’s overall health status is stable, but these conditions do require close monitoring, particularly when planning surgical procedures.

Clinical Examination:

On examination, the site of the missing tooth was noted in the lower right quadrant (46). The surrounding soft tissues appeared healthy with no signs of infection or inflammation. A thorough periodontal examination was conducted, revealing calculus buildup that required removal before proceeding with the surgical procedure.

Diagnostic Imaging:

A Cone Beam Computed Tomography (CBCT) scan was advised to evaluate the quality and quantity of the bone in the area, as well as to check for any proximity to the inferior alveolar nerve (IAN). This scan is essential in providing a detailed view of the bone structure, helping the clinician determine the appropriate implant size and position while avoiding damage to surrounding vital structures such as the inferior alveolar nerve.

Treatment Plan:

Given the patient’s history and examination findings, the treatment plan was established. The primary goal was to restore the missing tooth with a single dental implant in the lower right back tooth position (46). The dental implant will provide a permanent, functional replacement for the missing tooth and prevent further bone resorption that commonly occurs following tooth loss.

Surgical Procedure:

  1. Preoperative Preparation: Local anaesthesia was administered to ensure that the patient remained comfortable and pain-free during the procedure. An incision marking was made at the planned implant site to ensure precision during the flap elevation.
  2. Incision and Flap Elevation: A small incision was made in the gingival tissue over the planned implant site. A full-thickness flap was raised to expose the underlying bone. Care was taken to avoid damaging the soft tissues and to preserve the blood supply to the area for better healing.
  3. Pilot Drilling: A pilot drill was used to create an initial hole in the bone at the planned implant site. This step helps ensure that the implant is placed at the correct angle and position . The depth and direction of the drill were carefully measured to avoid any damage to surrounding anatomical structures, especially the inferior alveolar nerve.
  4. Sequential Drilling: A series of progressively larger drills were used to widen the hole to the appropriate diameter and depth for the implant. Each drill was carefully calibrated to ensure optimal bone density and an ideal fit for the implant.
  5. Implant Placement: After sequential drilling, the final dental implant was placed into the prepared site. The implant was inserted with careful attention to its position, ensuring it was stable and properly aligned with the surrounding teeth and bone. The implant was placed slightly below the bone level to allow for proper integration and osseointegration with the surrounding bone.
  6. Flap Closure: The soft tissue flap was repositioned over the implant site and sutured into place using absorbable sutures. This step was critical to ensure that the tissues healed properly and the implant remained stable.

Postoperative Care and Instructions: 

After the procedure, the patient was provided with postoperative care instructions, which included:

  • Pain management: The patient was prescribed pain relievers and anti-inflammatory medications to manage discomfort and swelling.
  • Antibiotics: A course of antibiotics was prescribed to prevent infection.
  • Dietary instructions: The patient was advised to follow a soft diet for the first few days to avoid placing stress on the surgical site.
  • Follow-up visits: A follow-up visit was scheduled within a week to check the healing process and remove any sutures if necessary.

Conclusion:

The surgical procedure for the placement of a single dental implant in the lower right back tooth region (46) was completed. The patient’s overall health status, coupled with careful surgical planning, ensured a smooth procedure. The use of diagnostic imaging, including CBCT, allowed for an accurate assessment of the bone quality and proximity to vital structures, such as the inferior alveolar nerve, minimizing any potential risks during surgery.

Dental implants are a reliable solution for tooth replacement, and this patient is expected to experience full recovery and integration of the implant. The next steps include allowing the implant to heal and integrate with the bone, followed by placing the final restoration once osseointegration is complete.

Note:

Given the patient's history of hypertension and diabetes, it's important to monitor their health throughout the healing process, ensuring optimal recovery and minimizing the risk of complications.
