Surgical treatment protocol

Surgical protocol	Bone quality
	D1	D2	D3	D4
1. Drilling sequence (splint)	Last drill	Last drill	Second to last drill	Second to last drill
2. Condensing preparation	–	–	(Analogue to last drill)	Analogue to last drill
3. Implant insertion (maximum torque ≤ 40 N cm)
4. Expansion (maximum torque ≤ 40 N cm)
5. Evaluation of primary stability by resonance frequency analysis, primary wound closure
6. Postoperative digital radiogram
7. Re-entry after a conventional period of submerged healing (mandible 3 months, maxilla 6 months), evaluation of secondary stability by resonance frequency analysis and insertion of healing abutments
8. Postoperative digital radiogram
