However, PI effects may be different based on the presence or absence of adjacent teeth. The objective was to investigate the differences in bone loss and inflammation between implants placed adjacent to a tooth or edentulous area in a ligature-induced PI model. Materials and methods include the following: Three-week-old C57BL/6J male mice underwent maxillary first (AT; n = 12) or first and second (AE; n = 8) left molar extractions. In both groups, implants were placed in the first molar region 8 weeks after tooth extraction. Each group was further divided into control (C) or ligature (PI) 4 weeks after osseointegration. The mice were euthanized 12-14 days after ligature placement. The samples were analyzed using micro-computed tomography and histology. Statistical analysis was performed using analysis of variance and Tukey multiple comparison test (P < .05). Radiographic linear analysis revealed no statistically significant differences in bone levels between the two C and PI groups. Linear bone loss was significantly greater in the PI group than in the C group. Volumetric analysis yielded similar results. Histologically, hematoxylin and eosin staining revealed no notable differences between the two C and PI groups. The PI groups showed increased levels of inflammatory infiltrates and bone resorption. Qualitative assessment of collagen through picrosirius red staining demonstrated increased collagen disorganization in the PI group compared with that in the C group. No notable differences were observed between the AT and AE groups. The presence or absence of an adjacent tooth does not influence PI-induced soft and hard tissue alterations.","PeriodicalId":519890,"journal":{"name":"The Journal of oral implantology","volume":" ","pages":"98-104"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142901412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A small handbook on blood sampling for dentists and oral surgeons in the dental practice has been published. The sole author of this guide is Prof. Shahram Ghanaati, DDS, MD, PhD, Senior Consultant and Deputy Director of the Department of Oral and Maxillofacial Plastic Surgery at Frankfurt University Hospital, Germany. Although the advantages of platelet-rich fibrin (PRF) and other blood concentrates in dental implantology are well known, dentists and dental assistants are not used to taking blood samples. The author presents a guideline for collecting and preparing blood samples to ensure a high level of patient safety in these cases and a certain degree of professionalism in the dental profession. In his foreword, the author rightly points out that only regular practice can bring theory to life. The soft-cover book is extremely compact at 64 pages. The author focuses on the individual work steps and points out possible application errors using 88 photos, illustrations, and generally very easy-to-understand language. The result is an inexpensive clinical guide describing the necessary equipment, anatomy, and the correct sequence of steps for successful venipuncture. It should be included in any oral surgery practice that wants to work with blood concentrates. Of course, anyone looking for references or further information in this small book will not find what they want in the instructions. A list of possible application areas for blood concentrates must also be made. However, the reader is provided with efficient step-by-step instructions. Thus, the booklet elegantly helps close the knowledge gap among dentists regarding successful blood collection.","PeriodicalId":519890,"journal":{"name":"The Journal of oral implantology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142848465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All systematic review studies showed that compared with traditional tobacco smoke, electronic cigarettes might reduce or not change the clinical inflammatory symptoms of periodontitis and peri-implantitis, such as bleeding on probing, probing depth, peri-implant bone loss, and response to treatments. Electronic cigarettes contain nicotine, which can harm periodontal and implant health. On the other hand, a wide range of oral health consequences may be associated with using e-cigarettes.

However, the formation of fibrous tissue prevents osteointegration and results in implant loosening. Thus, physical and chemical methods are used to improve the surface properties of Ti. This study aimed to understand the role of alkali treatment conditions, including alkali medium concentration, temperature, rotation speed, and post heat treatment. Our results show that alkali treatment using 5 and 10 molar sodium hydroxide (NaOH) solution allows the formation of web-like microstructure. However, a higher concentration of 15 molar resulted in cracks along the surface. Interaction between the human fetal osteoblast cells and Ti samples showed that heat treatment is necessary for increased cellular proliferation, which was not significantly different at later time points compared with the polished Ti. Alkali heat treatment did not induce inflammatory reactions at later time points. It showed an increase in vascular endothelial growth factor, osteoprotegerin/nuclear factor kappa-Β ligand ratio, and osteocalcin expression, which is evidence for accelerated osteoblast cell maturation and bone remodeling in surface-modified samples. Together, these data show that alkali treatment using 5 or 10 molar of NaOH followed by heat treatment may have a therapeutic effect and assist with bone tissue integration with Ti implant.","PeriodicalId":519890,"journal":{"name":"The Journal of oral implantology","volume":" ","pages":"636-643"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142127896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was a single-center, prospective trial and included adults aged 18 and above. From 2021 to 2022, 9 2-piece, tissue-level zirconia implants were placed in 8 patients. Following a 3-month osseointegration phase, crowns were cemented. Over a year, we assessed plaque and gingival indices, pocket depth, and tissue color and texture. Peri-apical radiographs measured bone levels, and IL-1β in peri-implant crevicular fluid was quantified using the enzyme-linked immunosorbent assay. Eight subjects (ages 31-63) participated. One implant failed after 6 months, resulting in a 1-year survival rate of 88.8%. Plaque and gingival indices rose, but peri-implant soft tissue remained stable in color and texture. At 12 months, average bone loss was minimal and insignificant compared with the baseline, and IL-1β levels were similar to those at contralateral teeth with no correlation between IL-1β, pocket depth, and bleeding on probing. Two-piece zirconia implants emerged as a viable tooth replacement option with an 88.8% 1-year survival rate. They maintained stable soft tissue and bone levels, indicating their potential as effective dental restoratives.","PeriodicalId":519890,"journal":{"name":"The Journal of oral implantology","volume":" ","pages":"563-568"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142038690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The patient is a 59-year-old female, who is a nonsmoker. At the initial visit, teeth #14, #15, and #17 were missing. After tooth #16 was extracted due to apical periodontitis, a bone defect with a diameter of approximately 4 mm was observed, leading to the formation of an oroantral fistula (OAF). Another window was created in the lateral wall adjacent to the superior part of the bone defect at the fistula site to achieve closure of the OAF through bone formation and simultaneously perform sinus floor elevation (lateral approach) for implant placement. Through this lateral window, instruments were inserted into the maxillary sinus towards the bone defect at the fistula site. During this process, the remaining bone between the lateral window and the bone defect at the fistula site was carefully removed with instruments, connecting the two bone defects to facilitate manipulation of the instruments. The Schneiderian membrane was elevated without enlarging the tear. Six months after these surgeries, a cone beam computerized tomography (CBCT) scan confirmed the closure of the fistula with hard tissue and the elevation of the sinus floor. Subsequently, three implants were placed, and prosthetic treatment was completed. Follow-up data is provided, including periapical X-ray and CBCT images taken 2 years and 3 months after surgery (1 year and 3 months after the placement of the final prosthetic structure).
