Come evidenzia una recente indagine condotta dall’osservatorio sul settore dentale dell’istituto di ricerche Key-Stone, nel 2024, in Italia, sono stati inseriti circa 2,2 milioni di impianti dentali (in aumento del 20% rispetto al 2019); si stima che fino al 40% di questi sia mal posizionato. Un dato che impone una riflessione approfondita sul ruolo che giocano la pianificazione chirurgica, la competenza dell'operatore e, non da ultimo, l'utilizzo di tecnologie avanzate.
Le conseguenze per i pazienti sono molteplici: prima fra tutte la funzione che, conseguentemente, determina anche l’estetica. Un impianto inserito in modo errato, infatti, può provocare un’eccessiva esposizione delle gengive, rendendo il sorriso disarmonico e causando altre complicazioni patologiche, prima fra tutte il rischio di perimplantite.
Quali sono quindi le principali cause del malposizionamento degli impianti e come intervenire per evitare questa problematica? Scopriamolo insieme in questo approfondimento di BioService.
Summary
The main causes of implant malposition
1. Inadequate surgical treatment planning
One of the most frequent causes is the lack of a thorough diagnosis and adequate prosthetic and surgical planning. The absence of upstream prosthetic planning can lead to implant placement that does not conform to the occlusal axis or the patient's aesthetic requirements.
2. Incorrect surgical techniques
During the surgical phase, errors such as excessive implant inclination or placement too close to sensitive anatomical structures can compromise the final result, leading to post-operative complications.
3. Professional inexperience
The training and experience of the practitioner play a central role. An international retrospective study co-ordinated by the Harvard School of Dental Medicine showed that the rate of implant failures is significantly higher among general practitioners than among specialists with advanced training in implantology.
4. Anatomy of the patient
Individual anatomical variables, such as gingival profile and the quality and quantity of available bone can influence correct implant placement.
5. Absence of surgical guides
The use of customised surgical guides s still too often underestimated. These tools, derived from digital surgical planning, allow accurate control of implant position, inclination and depth in prosthetic prosthetic function.

What are the solutions for predictable implantology?
- Careful planning
- Use of customised surgical guide
- Continuous training and professional education
- Multidisciplinary approach
Conclusion
Malpositioning of dental implants is not only an aesthetic problem, but a potential source of biological and functional complications. Preventing these errors is possible through accurate three-dimensional design, the use of digital surgical instruments and an interdisciplinary approach.
