Dr. Andrey Trokhalin leads the Surgical Department at SANABILIS Medical Center in Moscow. His clinical practice is focused on advanced implant rehabilitation for patients with severe jaw atrophy, failed implant treatment and complex full-arch rehabilitation. His work includes remote anchorage protocols using zygomatic, pterygoid, transnasal and trans-sinus implants, together with immediate loading and reconstructive techniques.
Professional background
Dr. Trokhalin began his surgical practice in 2013 at the Department of Maxillofacial Surgery of the Russian Center for Plastic and Reconstructive Surgery in Ufa. His early work included the rehabilitation of patients with severe jaw atrophy, traumatic injuries and defects associated with benign and malignant conditions of the maxilla and mandible.
He has completed training and internships in Italy, France, Portugal, Brazil, Sweden and Switzerland. In 2018, he received a PhD in medicine for research focused on the rehabilitation of patients with mandibular defects following benign and malignant resections. He is the author of more than 50 scientific publications.
Since moving to Moscow in 2021, he has led the oral and maxillofacial surgery department at SANABILIS. Alongside implant rehabilitation, he performs orthognathic surgery within a hospital head and neck surgery department.

Clinical case highlight: revision full-arch rehabilitation
This anonymized case demonstrates an individualized remote anchorage strategy in a patient with severe maxillary atrophy, previous implant failure and a defect involving the maxillary sinus.
Clinical case highlight: revision full-arch rehabilitation
- 60-year-old female patient.
- Chief concerns: mobility of the maxillary prosthesis, inability to chew adequately and difficulty smiling.
- Blade-form implants had been placed approximately 20 years earlier, with no dental follow-up reported during the previous 15 years.
- The patient was a non-smoker and had pharmacologically managed Type 2 diabetes mellitus.
- Clinical findings included peri-implantitis around the right maxillary blade-form implant and periodontitis affecting teeth #11, #21 and #23.
Diagnostic findings
CBCT evaluation showed severe atrophy of the maxillary alveolar ridge, together with a defect involving the floor and anterior wall of the maxillary sinus and thickening of the sinus membrane. The existing fixed prosthesis was supported by a combination of a blade-form implant, a cylindrical implant and remaining natural teeth.
Treatment planning rationale
The treatment objective was to restore function, aesthetics and prosthetic stability following the failure of the previous rehabilitation. Because of the severe maxillary atrophy, insufficient anatomical conditions for transnasal implants and unfavorable conditions for pterygoid implant placement, the selected plan used four zygomatic implants combined with one implant positioned in the incisive (nasopalatine) canal.
Clinical relevance
The case illustrates the importance of selecting implant positions according to the available anatomy rather than applying a fixed protocol to every patient. It also demonstrates the need to coordinate implant placement, defect closure, soft-tissue management and prosthetic planning in complex revision rehabilitation.
SANABILIS Medical Center
SANABILIS is a private multidisciplinary dental center in Moscow dedicated to comprehensive oral rehabilitation. In 2026, SANABILIS became certified as ZAGA Center Moscow-West. The clinic combines evidence-based dentistry, advanced surgical protocols and fully digital workflows within a team that may include maxillofacial surgeons, prosthodontists, orthodontists, endodontists, periodontists, TMJ specialists, dental hygienists, osteopaths and manual therapists, according to the needs of each case.
