“…36,37 The edentulous site enhancement (ESE) approach to increase soft tissue volume in mild or moderate defects has been described. 38 As illustrated in Figure 6, this involves making an incision on the crest, moving the flap facially, and stabilizing it with the provisional restoration (Figure 6). The wound then heals by secondary intention, resulting in increased keratinized gingiva (KG) dimensions.…”

“…The wound then heals by secondary intention, resulting in increased keratinized gingiva (KG) dimensions. 38 Connective tissue grafts, which can be sliced, folded, or unfolded, are another way to treat these defects and can be harvested from the palate or tuberosity. 39 It is essential to harvest high-quality soft tissue and understand its characteristics.…”

“…Mild to moderate defects can be corrected with soft tissue grafting alone, while larger ones may require multiple soft tissue reconstructions with or without hard tissue augmentation 36,37 . The edentulous site enhancement (ESE) approach to increase soft tissue volume in mild or moderate defects has been described 38 .

ObjectiveRidge deformities are present in most patients after tooth extraction; these defects make the management of future implant and pontic sites challenging to deal with. The restorative team should be able to diagnose and treat these deformities to allow for successful outcomes. Many approaches have been described to reconstruct pontic sites, each with specific indications. This article describes the different approaches to reconstructing pontic sites and their indications to allow for a proper esthetic and biological environment for future restorations.Clinical ConsiderationsDepending on the severity of the defect, location, and the esthetic necessity, pontic site enhancement can be done through different approaches, some requiring soft tissue grafting, hard tissue grafting, or both. Understanding the indications of the treatment options is essential to allow the clinician to make the right therapeutic decision and achieve the best possible perio‐prosthodontic outcomes.ConclusionsAn adequate balance between the soft tissue and prosthetics is essential to achieve successful results on implant‐supported or tooth‐supported fixed dental prostheses (FDPs). Selecting the right approach to treat ridge deformities is necessary to increase treatment success, reduce over‐treatment, and create a biologically sound environment for restorations.Clinical SignificancePontic site enhancement through reconstructive surgery will allow for esthetically pleasing and biologically stable results, allowing restorations to emulate natural structures lost after tooth extraction.

“…In Study I, III and IV the suprastructures were produced with an SM production in, while, in Study II, an AM laser melting technique was applied for a final Co-Cr framework melting on the pre-milled connection components with SM (Figure 12). The combination of the high-yield strength of Co-Cr and AM techniques increase the likelihood of restoring partial edentulous zones with implants even with limited space and different shapes 482 . However, Braian et al 240 reported concerns regarding the accuracy of the AM procedures.…”

Conventionally casted frameworks have been considered the preferredsolutions for complete and partial restorations since the beginningof implantology. However, following technological development, thecomputer aided design/computer aided manufacturing (CAD-CAM)with milling the frameworks has been introduced as an alternativeoption with the potential of minimising inaccuracies, reducing theoperator dependence and offering a homogeneous structure with highmechanical properties. The CAD-CAM multi-unit reconstructionvaries with fixation type, implant framework connection, andprostheses material. However, the materials developed for theuse of CAD-CAM, may have different technical and biologicalcomplications with time.The present thesis aims to provide insights into the risk ofcomplications in screw-retained multi-unit frameworks manufacturedusing the CAD-CAM technique. An in vitro test (Study I) was performed to assess the effectsof misfit at implant-level FPDs and supporting bone levels on thegeneration of implant cracks. Three clinical studies were conducted:in Study II, partially edentulous patients were rehabilitated with eitheran abutment or implant level multi-unit Cobalt-Chromium metalceramicframework; in Study III, patients, edentulous in the maxilla,were treated with either four or six implants and rehabilitated witha fixed titanium metal-acrylic framework; in Study IV edentulouspatients were treated with removable overdentures retained bytitanium milled bars. In Study III and IV, Oral Health Related Qualityof Life was evaluated.The marginal bone level change was clinically not significantregardless of fixation type (Study II), retention (Study III-IV), andmaterial used (Study II-III-IV). No framework complications wereregistered. Patients reported a high level of satisfaction after thetreatment (Study III-IV). Based on the studies included in this thesis, the followingconclusions can be made: (i) the risk of implant cracks in screwretainedImplant Level (IL) Fixed Partial Denture (FPD) is low, evenwith a misfit; (ii) according to the 1-year data presented in Study II,abutment level (AL) retention is recommended for FPDs; (iii) the costeffectivefor a maxillary Fixed Complete Denture (FCD) supported byfour implants can be considered predictable and comparable to siximplants; (iv) implant-supported FCDs and Implant supported Over-Dentures (IOD) are associated with high rates of patient satisfaction,related to aesthetics and mastication function mainly resulting fromthe high stability of the prostheses; (v) the technical and biologicalcomplications reported in FPDs, FCDs and IODs were limited.However, a considerable percentage of prosthetic fractures andchippings were reported for FCDs at 1-year and 3-year follow-ups.Clinicians have to be aware that additional visits may be required formaintaining the prostheses.
