Skeletal relapse after orthognathic surgery
Authors: Jan Rustemeyer
Published: July 2024

Orthognathic surgery, performed to correct functional and aesthetic jaw and facial irregularities, significantly enhances the quality of life for patients. Despite advancements in surgical techniques and computer-assisted planning, postoperative complications such as unintentional occlusion disorders and jaw misalignments remain common. Studies reveal postoperative jaw misalignments and malocclusions in approximately 10% of cases. Relapses after bimaxillary orthognathic surgery predominantly affect maxillary movements, especially in patients with cleft lip and palate, with up to 20% relapse due to scar contraction. Deviations from the preoperative plan occur even with advanced technologies, within generally accepted tolerances of less than 2 mm for translational and 2 degrees for rotational movements. The primary causes of relapse are linked to postoperative stability rather than planning accuracy, with contributing factors including the feasibility of orthodontic pre- and post-treatment, long-standing dysgnathia leading to tooth loss, and advanced patient age. These factors should be carefully considered to minimize the risk of relapse and improve surgical outcomes.

Authors: Si Ayu Komang Puspita Kencana Yasa  , Anita Yuliati  , Priyawan Rachmadi
Published: July 2024

Background: Tissue engineering is currently used as an alternative treatment to accelerate bone tissue regeneration. Composite scaffolds play a role in osteoinduction and can enhance cell proliferation. The addition of bone morphogenetic protein-2 (BMP-2) to the scaffold can promote cell migration, cell proliferation, and the differentiation of genes related to osteogenesis. Methods: This paper employs a narrative review and searches through PubMed, Sage Journal, and Science Direct for studies published in the last 5 years, using keywords such as "Bone Morphogenetic Protein-2," "BMP-2," "Composite Scaffold," and "Tissue Engineering," resulting in the identification of 20 relevant journals. Discussion: The release of BMP-2 on composite scaffolds enhances osteogenic differentiation and cell proliferation to accelerate bone tissue regeneration. Osteogenic differentiation occurs through the activation of the WNT/β-catenin pathway by BMP-2, which then promotes the migration of endothelial cells and osteoblasts to the surrounding tissue, thereby speeding up bone formation. Conclusion: The application of BMP-2 on composite scaffolds can be used for tissue engineering.

Aim: few studies exist on HLA-DRB1 alleles and their association with RA in North Africa. We aimed to provide an evaluation of the distribution of the HLA-DRB1* and -DQB1* genes in Moroccan patients with early RA. Additionally, we sought to analyze the relationship between HLA molecules and the production of rheumatoid factor (RF) and anti-cyclic citrullinated peptide antibodies (anti-CCP) in these patients. Methods: 65 patients with rheumatoid arthritis benefited from HLA class II typing (DRB1* and DQB1*) and testing for anti-CCP and RF antibodies. The frequency of HLA alleles was compared to that of 180 healthy controls. Logistic regression analysis was used to investigate the association of HLA-DR and -DQ molecules in the different subgroups according to anti-CCP and RF status. Results: The frequency of HLA-DRB1*04 and *11 alleles is increased in patients compared to controls (OR = 1.9; 95% CI (1.06-3.30), P=0.029; OR=2, 95% CI (1-3.83, P=0.047, respectively). 56 patients (86.1%) were RF positive, and 67.7% were anti-CCP positive. A significant increase in the frequency of DRB1*04 alleles was also noted in seropositive patients. Conclusion: Our results suggest the predisposition of the HLA-DRB1*04 allele and the seropositive status of patients with RA. This could be useful in predicting the evolution of RA and establishing a diagnosis in some patients at an early stage of disease use.

Introduction: Kombucha scoby shows potential as a biomaterial applicable to patients with head trauma that results in tearing of the dura mater layer. This research aims to characterize kombucha scoby with chitosan and collagen as in vitro modification materials. The artificial dura mater is derived from kombucha scoby synthesized in green tea media and added with glycerol as a plasticizer. Objective: This study used four composition variations: Scoby-Kombucha (Control), Kombucha-Glycerol, Kombucha-Chitosan-Glycerol, and Kombucha-Chitosan-Collagen-Glycerol. Characterization was performed based on functional group analysis through Fourier Transform Infrared (FTIR) testing, tensile strength, swelling, degradation, Scanning Electron Microscope (SEM), and (3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide) (MTT Assay). The characterization of functional groups confirmed the presence of functional groups from kombucha Scoby, chitosan, collagen, and glycerol. The data were analyzed using descriptive analysis. Results: The results of tensile strength characterization showed that the three sample composition variations have UTS values (4-20 MPa) and Elongation (7-20%) in accordance with artificial dura mater standards. The swelling characterization of the four samples showed a liquid absorption value that does not exceed the swelling ratio limit (<70%). The highest degradation was obtained in the Kombucha-Chitosan-Collagen-Glycerol sample composition with a degradation rate of 20%. The SEM test found a pore diameter that meets the standards for artificial dura mater in the sample compositions of Kombucha-Chitosan-Glycerol and Kombucha-Chitosan-Collagen-Glycerol. Cytotoxicity characterization through the MTT Assay showed that the material does not contain substances toxic to the body. Conclusion: The Kombucha-Chitosan-Collagen-Glycerol membrane was an optimal composition as a candidate for artificial dura mater.

Indonesia has 650 million tons of Buton Rock Asphalt (Asbuton) deposits. �The mineral residue, known as Asphalt Solid Waste (ASW). The extraction left ASW by 65-90% of asbuton�s weight. However, 770 thousand tons/year of ASW remain underutilized, causing environmental pollution due to its hydrocarbon content. Based on XRD results, Asbuton minerals were dominated with 46% CaCO3, which are potential as a subtitute material in concrete. However, its hydrocarbon content at 68,911 ppm raises concerns. To prevent ASW hydrocarbons from contaminating concrete, solidification was attempted. This study investigates solidification by making Artificial Coarse Aggregate (ACA) products and using ASW as a subtitute for gravel in concrete. The ACAs were produced from a mixture of ASW and cement, molded into 50 x 100 mm cylinders, crushed after twenty eight-days moist curing, and tested according to ASTM C33 standard of gravel. ASW replaced 0-12.5% by volume of sand and ACA replaced 0-12.5% by volume of gravel in concrete with a target compressive strength of 45 MPa at twenty eight-days. Heat of hydration and shrinkage were tested to indentify the impact of CaCO3 from ASW on concrete. The results showed that ACA could reduce 9% of ASW hydrocarbons. However, the ACA produced did not meet the gravel standard in ASTM because ACA absorption reached 6.75% and abrasion test up to 57%. Neverthless, ASW�s high absorption reduced heat hydration by 10% and shrinkage by 83% compared to normal concrete.

This study aims to perform technical calculations using precast lining in the repair of secondary channels. The planning data used included a concrete grade of fc 18.68 MPa and a reinforcement grade of fy 500 MPa. The service condition analysis was carried out by taking into account the loading during the most critical condition, where the channel is empty and active soil pressure and external water pressure are the main loads. The fixed load calculation was the main focus, where the active earth pressure (PD) was calculated by considering the soil-specific gravity, soil shear angle, and soil coefficient. The calculation results show that the PD reaches 12.24 kN, which gives an idea of the load that the structure has to bear. Furthermore, the internal force analysis provides a deeper understanding of the moments occurring at specific points in the structure. For example, the maximum negative moment at point A was calculated by considering the moments due to fixed load and transient load, which reached 12.73 kNm. This research contributes to improving efficiency and safety in the application of precast lining for secondary channel improvement.

Published: July 2024

Accurate three-dimensional (3D) models for Heritage Building Information Modeling (HBIM) remain a significant challenge. This paper proposes a methodology that combines the Poisson Surface Reconstruction (PSR) technique with open-source management software to address this issue. The methodology uses automatically generated mesh models to produce reality-based 3D models of historical buildings. These models are enriched with geometric and semantic parameters according to BIM standards. The resulting methodology, Scan to MesHBIM, is an open 3D interface allowing experts to analyze and create a detailed set of properties adhering to construction rules. To test the workflow, we selected two case studies of different vaulting types: the Renaissance barrel vault with cloister heads and lunettes from the Ducal Palace in Urbino (Italy) and the Gothic ribbed vault from St. André Cathedral in Bourdeaux (France). The use of implicit surfaces proved to be an efficient means for obtaining accurate 3D objects; then, the enrichment of the 3D models ensures a better understanding and more in-depth management in the field of Cultural Heritage (CH).

Currently, the majority of the Somali population does not have access to a regular source of power. The country does not have a national grid, relying on outdated, costly and inefficient diesel generators. The energy consumption in Somalia is dependent on firewood and charcoal, dependencies that rely on deforestation and desertification, which negatively influence the agricultural sector and also the environment. In this work, the potential of solar power in Somalia is assessed while estimating the cost of solar panels per household. This study aims to assess the cost, ecological and economic efficiency of the off-grid PV home system in residential buildings in Baidoa, Somalia. A stand-alone solar home system of 1.98kW PV capacity with battery backup is designed by using HOMER software. The daily primary load considered is 7.530 kWh, with a peak of the nominal power of 1.60 kW. The results show that renewable energy sources can replace conventional energy sources and that they would be a viable solution for generating electrical energy in residential houses in Baidoa with a reasonable investment. It was also found that the amount of power produced by solar panels is 7,400kWh/year. With an initial investment of $5580, the annualized life cycle cost of the system is $0.483, the payback period of initial investment is 2 years and 7 months period, and the net present cost (NPC) of the project is $18,684.

Concerns have been expressed regarding the issue of using conventional steel rebar in civil engineering structures. One contributing factor is the corrosion that occurred on the steel rebar. The corrosion process was not promptly detected due to the gradual reaction time exhibited by the steel, concrete, and environmental conditions. Corrosion problems often manifest when corrosion has progressed to a critical point and damaged the concrete structure. Consequently, to address this issue, this research proposed the application of carbon-fiber reinforced polymer sheet (CFRP). The aim is to measure the flexural load of conventional and FRP-reinforced concrete beams, to test the effects of cracking and deflection on concrete beams strengthened with FRP sheet, and to determine the degree to which these loads damaged these beams. A repair method was implemented by applying two distinct diameters of CFRP: 50 mm × 100 mm and 100 mm × 200 mm. The finding shows that the concrete beam's significantly higher flexural strength resistance was observed for CFRP of greater dimensions. This is mostly because the CFRP can disperse the applied stress more effectively. Alternative applications of fibre-reinforced polymer should be explored for further research to facilitate the development of substitutes for CFRP.
