(1) Background: Several studies showed a sustained temperature of 47 °C or 50 °C for one minute resulted in vascular stasis and bone resorption with only limited bone regrowth over a 3–4-week healing period. The purpose of the present study was to evaluate the temperature changes (ΔΤ) that occur during the preparation of dental implant osteotomies using MIS^® straight drills versus Densah^® burs in a clockwise (cutting) drilling protocol. (2) Methods: Two hundred forty (240) osteotomies of two different systems’ drills were prepared at 6 mm depth at 800, 1000, and 1200 revolutions per minute (RPM), in fresh, unembalmed tibiae, obtained by a female cadaver. ΔΤ was calculated by subtracting the baseline temperature on the tibial surface, from the maximum temperature-inside the osteotomy (ΔT = T_max − T_base). The variables were evaluated both for their individual and for their synergistic effect on ΔΤ with the use of one-, two-, three- and four-way interactions; (3) Results: An independent and a three-way interaction (drill design, drill width, and RPM) was found in all three RPM for the Densah^® burs and at 1000 RPM for the MIS^® straight drills. As Densah^® burs diameter increased, ΔΤ decreased. The aforementioned pattern was seen only at 1000 RPM for the MIS^® straight drills. The usage of drills 20 times more than the implant manufacturers’ recommendation did not significantly affect the ΔΤ. A stereoscopic examination of the specimens confirmed the findings. (4) Conclusions: The independent and synergistic effect of drills’ diameter, design and RPM had a significant effect on ΔΤ in human tibiae, which never exceeded the critical threshold of 47 °C.

Background/Aim: For the fabrication of a removable partial or a complete denture, it is important to reestablish the patient's individual occlusal plane and the vertical dimension of occlusion (VDO). Several methods have been described in the literature to determine the VDO for patients with complete dentures. For this purpose, in the early 1980s, Staub developed a software and a special series of appliances, the so-called Staub Cranial Analysis and Fabrication System for the fabrication of removable dentures as well as for the analysis of casts and existing dentures. The Staub Cranial System is based on defined anatomical reference points on the jaw model. According to Staub, these points should be present on every cast and unchangeable in their position. They are supposed to enable an exact indication of the former position of the natural teeth in a partially or edentulous jaw. Case Report: This paper analyzes the basic principles of Staub Cranial Analysis and presents the clinical application in a clinical case of a fully edentulous patient with initial not satisfactory prostheses. The paper describes in detail the step-by-step analysis process and the artificial teeth arrangement leading to a pleasing and natural set of dentures that anatomically fit in the stomatognathic system of the patient. Conclusions: New diagnostic possibilities, e.g. in orthodontics, prosthetic reconstructions, and implantology, could be implemented using this system. It also could be integrated in digital workflows for complete denture fabrication.

Objective: The Staub™ Cranial system is based on defined anatomical reference points of edentulous casts that can guide the reconstruction of artificial teeth on the edentulous jaw. The aim of this study was to evaluate the validity of the Staub™ Cranial system in reconstructing the position of natural teeth in edentulous maxillae. Materials and methods: To reconstruct the original position of natural teeth, 20 fully dentate maxillary casts were produced, and 20 duplicates had all teeth eliminated. Subsequently, following the Staub™ Cranial system guidelines, an artificial teeth set-up was completed. The measured distances included the intermolar width #16–26, the intercanine width #13–23, and the incisocervical length #11. Measurements were made using the principle of stripe projection with specially developed software. Original and reproduced casts were then compared. The reproduced casts with measured distances deviating less than 5% from the mean values of control models were considered successful reconstructions. Results: The ability of the system to reconstruct the original position of lost teeth in the edentulous jaw was precise. With a narrow tolerance range of 5%, 80% of the models could be reproduced with zero or a deviation in one dimension only. Conclusions: The results of this study confirmed the efficacy of the Staub™ Cranial system to provide guidance for the customized arrangement of artificial teeth in edentulous jaws.

Objective: The purpose of these two clinical cases reports was to present the variations in the surgical and prosthetic procedures related to an implant-supported fixed dental prosthesis (FDP) in the edentulous maxilla, following a fully guided implantation protocol and immediate loading. Case presentation: Two patients, one with terminal dentition and one with a completely edentulous maxilla, expressed the desire for immediate rehabilitation with an FDP and avoidance of multiple and complex surgical procedures. The clinical protocol for both cases included meticulous presurgical planning combining radiographic examination, diagnostic wax-up (conventional or digital), prosthetically driven digital planning of implant placement, fabrication of a surgical guide for fully guided implant installation, and delivery of a screw-retained fixed restoration. There was no report of any implant failure; the FDPs could be delivered as planned, and both patients expressed their satisfaction with the functional and esthetic outcomes. The clinical situation was stable at the recall.

(1) Background: Customized 3D-printed anatomical healing abutments (AHAs) are increasingly incorporated into digital implant workflows to optimize emergence profile development. However, the influence of tightening torque on their mechanical stability remains poorly understood. This prospective pilot clinical study evaluated the effect of different torque protocols on the stability of 3D-printed AHA placed on intermediate abutments. (2) Materials and Methods: Forty-two patients (52.4 ± 12.3 years) receiving 60 Paltop implants (Paltop Advanced Dental Solutions Ltd., Ashkelon, Israel) were included. Following implant uncovering, all implants received titanium intermediate abutments fabricated from a photopolymerized acrylate-based resin (MAZIC D TEMP; Vericom Co., Ltd., Chuncheon, Republic of Korea), torqued to 35 Ncm, and were allocated to four AHA tightening protocols. Clinical mobility, torque maintenance, and mechanical complications were evaluated at 4, 8, and 12 weeks. Group comparisons were performed using Fisher’s exact test. (3) Results: At 12 weeks, mobility occurred in 5/15 AHA (33.3%) in the hand-tightened group and 1/15 AHA (6.7%) in the 20 Ncm group, whereas no mobility was observed in 15/15 AHA (100%) in both the 25 Ncm and 30 Ncm groups. Mechanical complications differed significantly among groups (Fisher’s exact test, p = 0.047). (4) Conclusions: Tightening torques ≥ 25 Ncm provided superior early mechanical stability of 3D-printed AHA.

Bone resorption following tooth loss might compromise retention, stability, and support of conventional removable prostheses, and for this reason, implant‐supported overdentures are suggested as a viable alternative for completely edentulous patients. Bars, telescopic attachments, or stud attachments have been used to provide retention through a different mechanism of action based on specific design characteristics. The purpose of this report is to thoroughly describe the applied protocol for the fabrication of an implant overdenture supported by two bars incorporating stud attachments. A 67‐year‐old male patient presented to the Postgraduate Clinic of the National and Kapodistrian University in Athens seeking dental rehabilitation. The remaining teeth were characterized with poor prognosis, mainly due to their periodontal status. The proposed treatment plan included the placement of four implants in the maxilla and two implants in the mandible and the fabrication of implant‐supported overdentures. The diagnostic stages revealed adequate prosthetic space that would enable the fabrication of a bar substructure for the maxillary overdenture. To combine the benefits of bars and stud attachments, two bars with four attachments were fabricated. Evaluation of the delivered prosthesis revealed adequate retention, support, and stability achieved with minimal palatal coverage. Patient’s reported satisfaction and quality of life were increased. Recall appointments at one, six, and twelve months did not reveal any adverse effects or patient’s complaints. According to the present case report, different types of attachments may be used after careful study of each case. More studies are needed to report on different aspects of the chosen treatment plan.
