Special Issue Information

Dear Colleagues,

Oral and maxillofacial implants represent one of the most important fields of surgery, and are a fundamental aspect of oral and maxillofacial surgery. With this Special Issue I propose to focus on several topics related to the field: surgical complications, treatment of maxillary atrophy and oncological patients. I encourage you to share with the readers the state of the art in oral surgery.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The choice of an appropriate implant suprastructure, which should be made according to the individual characteristics of each patient, is a leading factor in achieving good aesthetic results. The aim of this study was to assess the clinical behavior of implant suprastructures according to functional, biological, and aesthetic criteria. Methods: The study enrolled 23 patients with a total of 27 implants in different areas of the oral cavity. The following groups were studied for a period of 1 year: Group A, the control group (monolithic implant crowns made of zirconium dioxide on a titanium base); Group B (monolithic implant crowns made of lithium disilicate with individualized (custom) titanium alloy abutment); and Group C (implant crowns made of zirconium dioxide with individualized titanium alloy abutment). The functional criteria included suprastructure fracture, crown fracture or chipping, screw fracture or loosening, faceting or wearing of the occlusal surface of the crown, articulation relations, and suprastructure fracture. The biological indicators included the probing pocket depth (PPD) and Mombelli et al.’s plaque index and bleeding on probing. The bone loss level was measured radiographically. Digital measurements of the bone loss level were performed when definitive prosthetics were placed and 1 year after. The platform of the implant was taken as a reference point. Two parallel lines ran distally and medially to the implant and descended to the level of the first thread, which was in contact with the bone. The aesthetic evaluation was based on Jempt’s papilla index and considered differences in the color of the peri-implant mucosa. The suprastructures were examined at 2 weeks and 1 year after the initiation of prosthetic treatment. Results: Regarding the functional criteria, no deviations from the reference range were registered in any of the study groups for both measurements. Radiography showed no bone loss in any of the study groups. Group B showed the best behavior regarding biological complications, followed by Group C. There was no plaque accumulation in Group B, but statistically significant amounts were found in Groups A (p = 0.08) and C (p = 0.01). Group B had the lowest bleeding index, but the differences between the groups were found to be insignificant during the observations at the one-year mark. On the vestibular side of the papillae, p = 0.39, while on the oral side, p = 0.35. The PPD measurements showed that there were statistically significant differences between the three groups when they were compared after the second week and after one year (p = 0.00). Jempt’s papilla height index showed the highest values in Group B, which increased by two times throughout the study period. The increase was statistically significant in Groups B and C, while the growth in Group A remained statistically insignificant (p = 0.10). The aesthetic indicator “Gingiva color around the restoration” showed mild margo gingivalis graying in Groups B and C. Conclusions: Individualized implant abutments made of titanium alloy and monolithic restorations made of lithium disilicate or zirconium dioxide have stable biomechanical behavior and may be the optimal choice for the prosthetic treatment of partial edentulousness. Because this study took place within a limited period of time, clinical trials with a longer follow-up period need to be carried out. Full article

During maxillary sinus augmentation (MSA), bone graft particles displaced through the perforated site can block the ostium and become a risk factor for maxillary sinusitis. The purpose of this case report is to introduce a novel approach for successful lateral MSA performed in the unrepairable perforation area of Schneiderian membrane. In a total of three patients, including two who were unintentionally treated with a split-mouth design, the Schneiderian membrane was irreparably perforated during the sinus floor elevation. After bone grafting was performed on only the sinus floor, the open lateral window technique was performed in which the upper part of the lateral window was opened. After the procedure, unexpectedly, the patient showed transient nasal bleeding, but no unusual clinical events. Most of the bone graft substitutes were not displaced and the exposed portion was covered with a soft tissue. In the sinus graft, clotting of blood, supplied from the perforated Schneiderian membrane and the buccal flap through the open lateral window, appeared to prevent graft displacement. Within the limitations of present case reports, these patients showed that MSA via the open lateral window technique was possible even with a widely perforated Schneiderian membrane that could not be repaired.
