Two implants placed in the same patient, using the same brand, can produce very different outcomes. The difference is surgical execution. Implant placement is a technique-sensitive procedure where the decisions made in the operatory — drill speed, final torque, implant angulation, flap management, proximity to anatomical structures — directly determine osseointegration quality, soft tissue outcomes, and long-term stability.
Flapless vs Flap Surgery: Choosing the Right Approach
The first surgical decision is whether to raise a tissue flap — cutting and reflecting the gum to directly expose the bone — or to proceed flaplessly through a small tissue punch. Flapless surgery preserves blood supply to the crestal bone, reduces post-operative swelling, and speeds recovery. It is appropriate when CBCT imaging confirms adequate bone volume and the implant trajectory is well-established by a surgical guide. Flap surgery is indicated when direct visualisation of the bone is clinically necessary — for example, when bone density is uncertain, when a bone graft is being placed simultaneously, or when complex anatomy is involved. At Dazzle, the choice is made case-by-case from the CBCT data, not by default protocol.
Drilling Protocol: Where Bone Viability Is Either Protected or Compromised
The drilling sequence that prepares the osteotomy is among the most consequential aspects of the procedure. Bone cells are heat-sensitive — temperatures above 47°C for more than 1 minute cause irreversible osteocyte death, which directly impairs osseointegration at the bone-implant interface. The variables that govern bone temperature: drill speed, irrigation volume and temperature, drill sharpness and sterility, and sequential step-drilling through progressively larger diameters. In softer bone (Misch Type III–IV), under-drilling condenses the bone rather than removing it, increasing primary stability without introducing heat.
Torque Control and Primary Stability Confirmation
Insertion torque is measured throughout implant placement using a calibrated implant motor. The target range for immediate loading is ≥35 Ncm. Over-insertion can cause bone necrosis from compression; under-insertion leaves the implant without sufficient primary stability for osseointegration. At Dazzle, insertion torque is recorded for every implant at every case. Resonance frequency analysis (ISQ measurement) is performed for cases where immediate loading is planned. The loading decision is made from these measurements, not from the pre-surgical plan alone.
Implant Positioning: Prosthetic-First Thinking
An implant positioned correctly for the bone may still be positioned incorrectly for the prosthesis. At Dazzle, implant positions are planned from the planned prosthesis backward — a “prosthetic-first” approach. The virtual surgical plan places implants where the prosthesis requires them to be, within the constraints of the patient’s bone anatomy. The surgical guide then physically constrains the drill to those positions during surgery.
Immediate vs Delayed Placement After Extraction
When a tooth is being extracted and an implant is to replace it, the timing of placement is a clinical decision with meaningful consequences. Immediate post-extraction implant placement reduces total treatment time, preserves socket bone architecture, and often allows immediate provisional loading. Delayed placement — allowing 6–12 weeks after extraction — is indicated when socket anatomy is unfavourable for primary stability or when infection must be resolved first.
FAQs
Q1: What is the risk of nerve damage during implant surgery?
With CBCT-guided planning and surgical guides, the inferior alveolar nerve and mental foramen are mapped precisely before surgery. Nerve proximity complications are rare when proper pre-surgical planning protocols are followed.
Q2: How long does implant surgery take?
A single-implant procedure typically takes 30–60 minutes. An All-on-4 full-arch case typically takes 2–3 hours per arch including extraction, implant placement, and provisional prosthesis attachment.
Q3: Does immediate placement after extraction affect success rates?
In appropriate cases — where the socket is infection-free and primary stability can be achieved — immediate placement has published success rates comparable to delayed placement.
Q4: What should I tell my surgeon before implant placement?
Any change in medications (particularly blood thinners, bisphosphonates, or immunosuppressants), recent illness, or change in systemic health status since your initial consultation.
