Anatomically Driven Immediate Implant Placement in the Esthetic Zone: Two Case Reports as Proof of Principle
Bibliographic record
Abstract
Achieving favorable and stable esthetic outcomes with immediate implants used to replace maxillary anterior teeth can be challenging. Osteotomies need to be initiated along the palatal socket wall, and it is often difficult to stabilize initial drilling. An immediate implant was planned for a hopeless maxillary incisor. Using a flapless surgery technique, the tooth was removed and decoronated, and an entry point was made in the root to guide the osteotomy drills. The root was reinserted and stabilized while a precision drill and 2-mm twist drill were used in sequence to drill through the tooth root, establishing the osteotomy location but stopping 3-4 mm short of final depth. The root was then removed, and the final implant bur for a 3.5 × 11.5-mm implant was drilled to depth, engaging the necessary native bone apically. The original tooth crown was then used to prepare and insert a transitional crown. Reinserting the extracted root of a maxillary anterior tooth and using it as a guide for osteotomy preparation is an excellent method to optimally position an immediate implant palatally in the socket wall.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
