Summary: This study evaluated the influence of thermomechanical cycling and type of abutment on the misfit and compressive strength of the implant-abutment interface. The results showed that thermomechanical cyclic loading aggravated the misfit, especially in completely cast abutments, regardless of material or fabrication technique, and reduced the compressive strength of the two types of abutments tested.

Summary: The study reported a case of dental implant failure with significant bone loss and described the use of reconstructive surgical techniques for treatment. A 58-year-old man with a history of implant surgery and mandibular implant failure was presented. Cone beam computed tomography (CBCT) and intraoral scans were used to collect data, which were exported into Exoplan software to obtain a standard tessellation file. A customized mandible mesh design was created using DentalCAD 3.0 Galway software. The method involved bone reconstruction and the application of a custom titanium mesh based on guided bone regeneration, using a bone mix obtained from a combination of xenograft, allograft, and autograft. Titanium meshes were fixed to the bone with self-drilling screws and covered with a resorbable membrane. An impression was recorded immediately after surgery, and the patient received a milled polymethyl methacrylate interim denture the next day. According to the case study, the custom-made implant can be considered a temporary solution, allowing for guided bone regeneration to take place.

Summary: This study aimed to evaluate the survival rate, marginal bone levels, and full arch prosthetic success of short implants in severely resorbed and edentulous mandibles. A systematic review of three relevant studies found short-term dental implant survival rates ranging from 94.2% to 97.4% with a five-year follow-up, and prosthetic success rates around 62% during the same follow-up. The mean marginal bone level values of the affected short implants ranged from 0.2 mm to 0.6 mm. It was concluded that short dental implants positioned with precision as a full-arch fixed support are a valid therapeutic choice for medium-long-term rehabilitation of severe edentulous mandibular atrophy.

Summary: This study validated a mathematical rule based on soft tissues thickness for choosing the correct implant position to prevent marginal bone loss and bacterial colonization. Implants inserted according to this rule in the Biological Oriented Immediate Loading protocol showed 100% survival rate after 5 years with minimal marginal bone loss. The use of Multi Unit Abutment also contributed to a stable biological seal and successful healing of implants.

Summary: Concerns have arisen recently about potential deformations and fractures of titanium implants, despite their widespread use in orthopedic and dental surgeries. In a recent clinical case, a titanium implant fractured after successful osseointegration, even without significant trauma or excessive external force. Factors including design flaws, material fatigue, and biomechanical stress during functional loading contribute to such fractures. This raises concerns about the long-term durability and reliability of titanium implants, especially in high-stress areas.

Summary: Insufficient evidence currently exists to validate a correlation between dental occlusion disorders and spinal curvature, prompting the need for further studies. This controlled study on rats induced malocclusion in rats' mouths to investigate changes in vertebral alignment over time, revealing a potential relationship between occlusal contact and body posture. The study found that unilateral occlusion changes in the molar region resulted in rotation of the lumbo-sacral segment towards the same side as the occlusal bite-raising.

Summary: The aim of this study was to compare the damaging effects of two xenografts with different resorbability rates on the Schneiderian membrane (SM). The results showed that the deproteinized bovine bone mineral (DBBM) group had more damage compared to the swine collagenated corticocancellous bone group. Furthermore, inward displacement of the bone window and placement of a collagen membrane adjacent to the SM offered protection from damage.

Summary: The study aims to describe the histological events following maxillary sinus floor elevation when the elevated and undetached sinus mucosa are in close proximity or in contact with each other. Histological analysis of 152 elevated maxillary sinuses from 76 rabbits was conducted. The results showed that the width of the pseudostratified columnar epithelium and the distance between the two layers of the elevated and undetached sinus mucosae were measured at different standardized positions. Adhesion of the mucosa was observed in 31 sites, with 12 sites in the proximity stage showing shortened cilia and interlinked epithelial layers, as well as hyperactivity of goblet cells. Fusion and synechia stages were also observed.

Summary: This study analyzed the morphology of bone graft granules and bone tissue in retrieved maxillary sinus bone graft biopsies. The results showed that the bone graft granules were mainly found in the apical region, while new bone tissue bridges were detected in the apical and middle regions. These structures with lower mineralization ratios were connected to and enveloped the bone graft granules. The cortical region exhibited the highest level of mineralized bone tissue. The study concluded that after 9 months, bone graft resorption was only partially completed and new bone tissue appeared less mineralized in the middle and apical regions compared to the coronal region.

Summary: This systematic review compiles the post-operatory complications of sinus elevation with bone grafting and functional endoscopic maxillary sinus surgery (FESS), including voice changes, and determines that those changes are temporary. The review found that complications are frequent after sinus lifting with bone grafts and FESS, while voice parameters are rarely evaluated after sinus lifting with bone grafts and no voice changes are reported. Voice changes that occur after FESS include decreased fundamental frequency, increased nasality, and nasalance, which are all transient.
