Purpose: The objective of this prospective randomized clinical trial (RCT) was to analyze and compare the clinical behavior of three types of prosthesis supported by single implants in the posterior region after three years of functional loading. Materials and methods: Seventy-five implants were divided into three groups according to the type of prosthetic restoration: screw-retained crown (group GS); cemented crown without finishing line (biologically oriented preparation technique) (group GBOPT); and conventional cemented crown with finishing line (group GCC). After three years in function, clinical parameters (presence of keratinized mucosa, probing depths, bleeding on probing, and radiographic bone loss) were compared between the three experimental groups. The possible correlation between soft tissue clinical parameters and bone loss was also analyzed. Results: Statistical analysis found significant differences in clinical parameters between the different types of crown, with the cemented restoration without finishing line (BOPT) presenting fewer complications and better peri-implant health outcomes including: significantly different KMW data (mm), with significant differences between groups GBOPT and GCC (p < 0.001, Kruskal–Wallis test), with GBOPT obtaining larger quantities of keratinized mucosa (KM); statistically significant differences in probing depth (PD) values between groups GBOPT and GCC (p = 0.010, Kruskal–Wallis test); significant differences in bleeding on probing (BOP) between groups GBOPT and GCC (p = 0.018, Chi2 test) in favor of GBOPT. Conclusions: Soft tissue behavior around implants is related to the type of prosthetic restoration used, with cemented prostheses with BOPT presenting better peri-implant soft tissue behavior.

Background: Tooth extraction is one of the most commonly performed procedures in dentistry. It is usually a traumatic process often resulting in immediate destruction and loss of alveolar bone and surrounding soft tissues. Various instruments have been described to perform atraumatic extractions which can prevent damage to the paradental structures. The physics forceps is one of those innovations in dental extraction technologies that claim to provide an efficient means for atraumatic dental extractions. Materials and method: A randomized clinical trial was conducted to compare the physics forceps with the conventional forceps for the removal of 28 mandibular single rooted teeth under the following parameters: incidence of crown, root, buccal alveolar bone fracture, the incidence of gingival tear and time needed for extraction. The samples were assigned randomly into two groups according to the computer based randomization software, into a control group (A) and study group (B). The control group was subjected to the surgical extraction procedure using the conventional forceps while the study group was subjected to the surgical extraction procedure using the physics forceps. Results: results showed that the time required for extraction using the physics forceps was (mean 0.385 min.), which was significantly lesser as compared with that of conventional forceps (mean 3.971 min.) (P=0.011), buccal bone fracture occurred in 4 out of 14 cases (28.57%) using the conventional forceps while it did not occur with the use of the physics forceps (0.00%), crown fracture occurred in 3 cases using the conventional forceps (21.43%), while it did not occur with the use of the physics forceps (0.00%), root fracture occurred in 1 case using the physics forceps (3.57%), while it did not occur with the use of the conventional forceps (0.00%). As for the gingival tear, it occurred in 7 cases using the conventional forceps (50.00%), while it did not occur with the use of the physics forceps (0.00%) which was highly significant (P=0.006). Conclusions: the use of physics forceps maintains the integrity of gingiva and surrounding periodontium. So extractions using physics forceps are less invasive over conventional forceps and can be considered as a reliable method for extraction requiring significantly less comparative intraoperative time.
