This educational case, presented by Dr. Ivo Erthal through Desafios da Implantologia, reviews a complete upper-arch implant rehabilitation workflow from a procedural reasoning perspective. The case follows the sequence of anesthesia, dental extractions, flap design, mucoperiosteal reflection, socket curettage, alveolar bone reduction, use of a multifunctional guide, implant site preparation, implant placement, and selection of straight and angled conical mini-abutments.

The lesson emphasizes anatomical and prosthetic considerations in the maxilla, including management of the palatal and vestibular tissues, attention to the nasopalatine region, assessment near the maxillary sinus and nasal cavity, and the role of bone leveling in prosthetic space, hygiene access, smile-line planning, and future prosthesis adaptation.

The content also discusses the use of a multifunctional guide as part of reverse planning, implant angulation control, distribution of implants in an All-on-4-style configuration, and intraoperative verification steps such as probing the osteotomy and checking for possible sinus communication. The focus is educational and intended to support clinical reasoning, anatomical awareness, and structured procedural review.
