- This experiment was conducted to study the histologic feasibility and biologic impact of Ti02 impregnation of an extracellullar matrix (ECM) membrane in guided bone regeneration. Eighteen adult New Zealand White rabbits were used. Bilateral bone defects were created in edentulous areas of the maxilla. The defects were filled with demineralized freeze-dried bone (DFDB). ECM was randomly pretreated with a suspension containing saline and 3 mg Ti02 granules. A regular ECM membrane served as a control on the contralateral side. Healing periods were 2, 4, and 8 weeks. Histologic and histomorphometric analyses were performed. The parameters assessed were (1) zone of inflammatory cells adjacent to ECM membrane, (2) presence of cellullar ingrowth into ECM, and (3) presence of Ti02 particles within the ECM barrier membrane. In general, no adverse reactions toward both groups of ECM membranes could be noted. The Ti02 particles remained within the ECM after 8 weeks of healing, making histologic detection of ECM easy. Histomorphometric analysis revealed low numbers of inflammatory cells adjacent to the ECM surface and adequate preservation and integration of the barrier. Contrasting Ti02 particles impregnated into the ECM membrane can be a very useful tool for the detection of similar biologic materials in in vivo models.

- The aim of this report was to describe the bone tissue response to Branemark oral implants retrieved from patients. The material consisted of consecutively received Branemark threaded oral implants and related patient data provided by clinicians. The implant samples were processed into undecalcified sections for evaluation under the light microscope. The analysis demonstrated a lower percentage of bone-to-implant contact for the unloaded implants as compared to the loaded implants. When the threads were divided into four different regions, the loaded implants had a lower percentage of bone-contacting length at the thread top as compared to the other three regions.

Modified free gingival graft technique for root coverage at mandibular incisors: A case series

Tidskriftsartikel (refereegranskat)abstract
- Numerous surgical techniques for root coverage have been suggested with different degrees of success, as assessed by the proportion of complete root coverage. Mandibular incisors, teeth with a high frequency of gingival recession defects (GRDs), were associated with the least favorable outcomes due to unfavorable anatomical conditions. In the present series of three cases, a modified version of the free gingival graft technique for the purpose of root coverage at mandibular incisors is illustrated. The purpose of the modification of the original technique was to achieve improved blood supply from the recipient site to the graft, with the ultimate aim of enhancing predictability and outcomes of the procedure. In all included cases, complete or almost complete root coverage was achieved at challenging GRDs in the mandibular incisor area.

- This investigation was designed to evaluate crestal bone stability and soft tissue maintenance to Laser-Lok tapered tissue-level implants. Twelve patients presenting with an edentulous site adequate for the placement of two implants were recruited from four dental offices (2 to 4 patients per office). Each patient received two Laser-Lok tissue-level implants placed with a 3-mm interimplant distance according to a surgical stent. The implants were placed so that the Laser-Lok zone sat at the junction between hard and soft tissues. A total of 24 implants were placed, and all achieved satisfactory crestal bone stability and soft tissue maintenance 1 year after receiving the final prosthetic restoration.

Decontamination of Customized Laser-Microtextured Titanium Abutments: A Comparative in Vitro Study of Different Cleaning Procedures.

- The aim of this study was to evaluate different cleaning procedures for customized laser-microtextured titanium abutments. A total of 20 customized laser-microtextured abutments were randomized into four groups: no cleaning (control group), ultrasonic treatments + autoclave cycle (group 1), ultrasonic treatments + argon plasma (group 2), and only argon plasma (group 3). Surface contaminants were assessed through scanning electron microscopy and energy-dispersive x-ray spectroscopy microanalysis. In the control group, 99.96% of the abutment surfaces were contaminated with organic and inorganic pollutants. Group 3 showed the second highest contamination percentage, with almost 23% of the analyzed surfaces polluted. Samples in groups 1 and 2 were almost clean, with negligible traces of microparticles (0.009% and 0.047% of the surfaces were contaminated, respectively). These results were statistically significant for differences between control and test groups, and between groups 1 and 2 in comparison to 3 (P < .001). Abutment decontamination with argon plasma alone might not be as effective on laser-microtextured surfaces as other cleaning protocols.

A prospective study comparing the effect of L-PRF and porous titanium granules on the preservation of the buccal bone plate following immediate implant placement

- The aim of this study was to compare the effect of an autogenous blood concentrate (L-PRF) with the effect of white porous titanium granules (WPTG) on buccal bone remodeling. These materials were used to graft the void between the implant and the buccal bone following immediate implant placement. Clinical measurements were made at two time points, and the mean buccal bone horizontal dimension at placement was 2.94 ± 0.59 mm for L-PRF and 3.49 ± 0.99 mm for WPTG. At reentry, the values were 1.19 ± 0.90 mm and 2.12 ± 0.87 mm, respectively. Overall, there was no difference observed in the performance of the two materials regarding buccal bone resorption.

The Influence of Initial Hard and Soft Tissue Dimensions on Initial Crestal Bone Loss of Immediately Loaded Dental Implants
- 2018
-
Ingår i: The international journal of periodontics & restorative dentistry. - : Quintessence Publishing Co. Inc.. - 0198-7569 .- 1945-3388. ; 38:6, s. 873-878

Tidskriftsartikel (refereegranskat)abstract
- The aim of this case-control study was to evaluate the influence of soft tissue thickness at implant placement (thin [< 3 mm] vs thick [>= 3 mm]) and bone volume (abundant vs limited) on initial crestal bone remodeling of immediate postextraction and delayed (healed site) implants in immediate loading situations. A total of 67 patients with 133 implants could be evaluated, of which 77 were placed immediately after extraction and 56 in healed ridges. If sufficient bone volume is present and primary stability is achieved, immediate loading of the implant yields good clinical and radiographic outcomes, yet implants placed in healed ridges with thin soft tissues are more prone to initial crestal bone loss.
