Endodontic retreatment and bioceramics: A case report.

J Biol Regul Homeost Agents 2021 May-Jun;35(3 Suppl. 1):147-153

Department of Social Dentistry and Gnathological Rehabilitation, National Institute for Health, Migration and Poverty (NIHMP), Rome, Italy.

The success rate in endodontic retreatment can be significantly boosted by using materials that guarantee both intimate adhesion to the canal walls and long-term stability. Bioceramic cements used in root filling show interesting properties including extraordinary sealing capacities, antimicrobial activity that stimulates periapical healing and the continuous production of hydroxyopathitis for a long time. This case report deals with the application of bioceramic cement in endodontic retreatment. The Bioroot RCS (Septodont), thanks to its ability to firmly adhere both to the gutta-percha and to the walls of the canal and to definitively seal the apical third, can allow to obtain extraordinary healing in a relatively short time by exploiting its antimicrobial abilities. However, further studies are needed to assess the effectiveness of this technique over the long term.

Guided sinus lift: virtual planning of surgical templates for lateral access.

J Biol Regul Homeost Agents 2021 May-Jun;35(3 Suppl. 1):139-145

Department of Social Dentistry and Gnathological Rehabilitation, National Institute for Health, Migration and Poverty (NIHMP), Rome, Italy.

The sinus lift with lateral approach is a regenerative technique nowadays considered predictable to increase the height of bone in the atrophic posterior maxilla. Knowledge of sinus anatomy and evaluation of risk factors are the basis of regenerative and rehabilitative surgical success. The positioning and size of the lateral antrostomy represent critical factors in the execution of regenerative surgery, due to the difficulty in transferring radiological information to the lateral wall of the maxillary sinus even for skilled surgeons. The knowhow of guided implant surgery in recent years is also finding use in planning and precisely delineating the lateral access to the maxillary sinus using CBCT imaging and dimensional reconstruction software, through the realization of surgical guides with 3D printing, as shown in the presented case.

Critical investigation of the pre-surgical anatomic factors that influence the aesthetic result in post-extractive implantology and immediate prosthetic.

J Biol Regul Homeost Agents 2021 May-Jun;35(3 Suppl. 1):127-137

Private Practice, Rome, Italy.

The aesthetic goals of implant dentistry should be similar to those of conventional prostheses. In implant-prosthetic rehabilitations of the anterior sectors, the quantity and quality of hard and soft tissue play a fundamental role in achieving the desired aesthetics and in integrating the restoration in a complete and harmonious way into the existing anterior dentition. Post-extraction implantology is a treatment option for implant therapy after the extraction of a single tooth in the anterior jaw. This article presents some key factors to analyze and follow in order to achieve a predictable and acceptable aesthetic result. The creation of a predictable peri-implant aesthetics requires adequate preservation of the bone and soft tissues around the teeth that will be extracted and a correct positioning of the 3D implant. Furthermore, aesthetic success requires the creation of a correct transmucosal path, during the provisional prosthetic phases, which must be replicated and maintained with the definitive crowns.

Appearance of normal MRI anatomy of the lingual nerve using steady-state free precession sequences at 3-T.

J Biol Regul Homeost Agents 2020 May-Jun;34(3 Suppl. 1):19-26. DENTAL SUPPLEMENT

Dept. of social dentistry and gnathological rehabilitation, National Institute for Health, Migration and Poverty (NIHMP), Roma, Italy.

The aim of this study is to assess the value of SSFP MRI sequence in depicting the normal anatomy of the lingual nerve (LN), particularly in the molar region, in order to help the periodontists, dentists and oral surgeons in their daily practice. The study group included 24 patients who were to undergo MR study for a reason unrelated to our purpose. All imaging was performed by using a 3.0T system with a head and neck multiarray coil. The evaluation criteria included image quality factors such as the identification of the LN, its demarcation and its contrast to surrounding tissues on a five-point scale. The LN is clearly visible throughout its course from its origin from the mandibular nerve (MN) to the mylohyoid muscle. In edentulous patients, the LN could be damaged during surgical procedures especially it during the dissection and retraction of a lingual flap and, above all, during the suture due to a direct trauma caused by the needle or indirectly during tying the knot.

Computer-guided implant surgery: analysis of dynamic navigation systems and digital accuracy.

J Biol Regul Homeost Agents 2020 May-Jun;34(3 Suppl. 1):9-17. DENTAL SUPPLEMENT

Dept. of social dentistry and gnathological rehabilitation, National Institute for Health, Migration and Poverty (NIHMP), Roma, Italy.

After the static computer-guided implant surgery, borns the concept of "navigated implantology" (NI) that offers significant advantages in the treatment planning and help clinicians to perform successful implant rehabilitation. NI allows an optimal final location, to avoid the risk of damaging the noble anatomical structures near the site and allows the achievement of satisfactory aesthetics. The aim of this study is analyze three different systems: the RoboDent® system (Berlin, Germany, 2001), today not for sale, was the first implant navigation system introduced on the market and made the history of dynamic surgery; X-Guide (Nobel Biocare, 2017), a dynamic computer assisted system that uses the principles of stereoscopic triangulation by optical video cameras. And last, the Navident® dynamic navigation system (Toronto, Canada, 2015), produced by the Canadian company ClaroNav, evolved from the Navient brand used in orthopaedic surgery, neurosurgery and otolaryngology, sharing the motion tracking technology. Dynamic computer assisted surgery systems allow more accurate implant placement when based on an accurate 3D CT-based image data and an implant planning software which minimizes errors and simplify the surgical technique.
