HISTOMORPHOMETRIC AND IMMUNOHISTOCHEMICAL EVALUATION OF BONE HEALING AROUND IMPLANTS PLACED USING PIEZOSURGERY VS CONVENTIONAL DRILLS: A SPLITMOUTH PILOT STUDY.
J Oral Implantol
January 2025
Department of Neuroscience, Reproductive Sciences and Dentistry, Federico II University of Naples, Naples, Italy.
Purpose: This pilot study evaluated and compared histomorphometric and immunohistochemical characteristics of peri-implant bone tissue after implant site preparation using piezoelectric tips versus conventional drills.
Material And Methods: Six patients with bilateral partial edentulism underwent a splitmouth protocol. Twelve alveolar ridges were randomized into six control implant sites prepared using conventional drills (Drill Group); and six test implant sites prepared using piezoelectric implant inserts (Piezo Group).
Reducing Healing Period with DDM/rhBMP-2 Grafting for Early Loading in Dental Implant Surgery.

Department of Oral and Maxillofacial Surgery, Section of Dentistry, Seoul National University Bundang Hospital, 172 Dolma-ro, Bundang-gu, Seongnam-si, Gyeonggi-do, 13620, Republic of Korea.
Background: Traditionally, dental implants require a healing period of 4 to 9 months for osseointegration, with longer recovery times considered when bone grafting is needed. This retrospective study evaluates the clinical efficacy of demineralized dentin matrix (DDM) combined with recombinant human bone morphogenetic protein-2 (rhBMP-2) during dental implant placement to expedite the osseointegration period for early loading.
Methods: Thirty patients (17 male, 13 female; mean age 55.
Evaluating the microgap and sealing capability in four implant systems with different interlockings under different tightening torques: an study.

December 2024
Department Prosthetic Dental Sciences, College of Dentistry, Jouf University, Jouf, Saudia Arabia.
Purpose: This study assessed the microgap width and adhesion of three bacterial species in four dental implants with different interlocks under four screwing torques.
Materials And Methods: Ten samples of four implant systems with various interlockings, including full-hexagonal (FHI), cylindrical-conical trilobe-index (TLI), Morse-taper with octagon terminal index (OI), and hexagonal interlock (slip-fit) (HI-SF), were used. The abutments were screwed to the fixtures under torques of 10, 20, 30, and 40 Ncm.
Effect of Cyclic Loading on the Fixture-Abutment Microgap in Short Implants Versus Standard Implants: An In Vitro Study.

Department of Prosthodontics, Faculty of Dentistry, Tehran Medical Sciences of Azad University, Tehran, Iran.
This study aimed to assess the effect of cyclic loading on the amount of fixture-abutment microgap in short implants compared to standard implants. This in vitro experimental study was conducted on two groups of short and standard implants ( = 10). The microgap at the fixture-abutment interface was measured under a light microscope at ×75 magnification.

Article Synopsis
- The study aimed to assess the long-term outcomes of one-piece narrow-diameter implants (NDIs) and identify factors influencing marginal bone loss (MBL) around them.
- The analysis involved 25 patients and 40 NDIs over an average of 10.5 years, with a high survival rate of 95.1% for implants and a mean MBL of 0.44 mm, primarily linked to the use of guided bone regeneration (GBR).
- The findings suggest that NDIs perform well clinically over time, showing acceptable MBL, but further research with larger samples is recommended to confirm these results.
