“…Standardized procedures can certainly facilitate comparison. Nevertheless, regarding the impact of implant placement and loading time, it was concluded that prosthetic loading does not affect the MBL in implants placed in healed sites [60]. One limitation of the present review is that the primary aim of the studies from which the data were extracted and compared was different from that of this review.…”

Currently, one of the most important challenges in dental implant surgery is the optimization of techniques to obtain a high grade of stability. This is a key factor for survival and long-term predictability, especially in immediate loading procedures [1]. Implant stability can be classified as primary and secondary, which represent the mechanical retention of the bone at the time of implant insertion and the formation of biologically stable bone around the fixture, respectively [2,3].A commonly used surgical protocol to obtain increased primary stability consists of under-dimensioning the preparation of the site, especially in the case of low-density bone. With this technique, also called underpreparation or underized drilling, an implant is inserted in a substantially smaller osteotomy than its diameter, and is typically obtained by skipping the use of the last drill from the drilling protocol. This leads to an immediate direct contact of the implant surface with the bone, which promotes primary stability, and is clinically perceived as insertion torque (ITQ) [4]. The initial bone-toimplant contact then undergoes a major change during the healing period and while functioning. The increased lateral compression induced by underpreparation might affect the local microcirculation and bone cellular responses, leading to bone compression necrosis [5]. A review by Insua et al. [6] clarified the bases of bone metabolism during implant healing and the processes that can lead to peri-implant bone loss. The review consistently demonstrated, from a cel-J Prosthodont Res. 2022; **(**):

“…In addition, an open-flap approach allowed for the extension of the indications for this type of implant rehabilitation. Implant installation following an International Team of Implantology (ITI) type I or type II protocol [ 21 ], immediate provisionalization, and alveolar defect augmentation during a single surgical intervention offer incontestable advantages for both dental professionals and patients.…”

In this case report, we aimed to describe a novel approach for aesthetic rehabilitation of the anterior maxilla that combined immediate implant installation with the “Bone2Soft Tissue Reconstruction” (B2S technique), which involves the use of a triple graft harvested from the maxillary tuberosity. The regeneration potential of a tuberosity graft appeared to surpass that of corticocancellous bone grafts harvested from other intraoral donor sites and allowed for quicker regeneration of both bone and soft tissue. The B2S technique extended the indications for immediate implant placement and ridge augmentation to cases involving severe bone resorption and other complex clinical scenarios. Owing to the good visualization facilitated by open-flap access, the surgical procedures can be completed in a single intervention, which will be beneficial for both doctors and patients.

Introduction The patient-centered SafetyCrown-workflow enables the immediate restoration of posterior missing teeth and short free-end situations following one-abutment/one-time within three visits and only one surgical approach. This prosthodontic rehabilitation aims to combine the advantages of cemented and screw-retained restorations. Report The concept has been performed with 4 restorations in 3 patients and followed up for up to 1 year (mean: 11.2 months) without technical and/or biological complication. Visit 1: Intraoral optical impression, CBCT, and tooth shade selection. Virtual implant planning is performed, and a surgical guide is printed. After exporting the planned implant position, a tooth-colored abutment is fabricated from zirconia with a 1-mm supragingival cementation line, adhesively bonded to a titanium base. Visit 2: Fully navigated implant placement with insertion of the definitive abutment. Subsequently, optical impressions are prepared for A: immediate restoration using a PMMA crown without functional contacts; B: definitive crown fabricated from monolithic zirconia and individualized. The localization of the screw channel is marked using stain thus permitting precise screw channel access, if necessary. Visit 3: After osseointegration of the implant, the definitive crown is adhesively cemented supragingival. In a retrospective analysis of PROMs (‘How stressful was the treatment process […]?’ (0 = not stressful at all, 100 = very stressful), mean VAS score for SafetyCrown of 14 (SD 11.7) and 29.8 (SD 23.1) for standard procedure were present. Conclusion The SafetyCrown offers a shortened, patient-oriented concept for implant-supported single-tooth reconstructions omitting second-stage surgery. Clinical performance and hypothesized prosthodontic benefits require confirmation via an RCT.
