"Kehilangan gigi telah menjadi salah satu permasalahan yang umum untuk ditemukan di Indonesia, dengan angka sekitar 19% kasus gigi hilang akibat dicabut ataupun tanggal sendiri. Untuk mengatasi permasalahan kehilangan gigi, implan gigi merupakan alternatif yang banyak digunakan karena sudah terbukti dapat memberikan hasil yang baik secara jangka panjang. Keberhasilan pemasangan implan gigi dinilai berdasarkan tingkat stabilitasnya, yang terbagi kembali menjadi stabilitas primer dan stabilitas sekunder. Kedua jenis stabilitas tersebut saling berkaitan. Kekhawatiran akan pemasangan implan gigi banyak ditemukan pada kasus dimana pemasangan dilakukan pada pasien dengan tulang berkepadatan rendah. Tulang tempat terpasangnya implan gigi yang memiliki kualitas dan kepadatan yang kurang baik memiliki risiko kegagalan implan yang lebih tinggi. Untuk dapat meningkatkan tingkat stabilitas implan, banyak dilakukan proses modifikasi desain dan permukaan implan gigi, seperti penambahan fitur self-tapping dan peningkatan kekasaran permukaan badan implan. Fabrikasi dilakukan untuk menghasilkan purwarupa implan gigi dengan variasi sudut kemiringan dan panjang cutting flute, sebagai bagian dari fitur self-tapping. Purwarupa akan melalui proses surface treatment untuk mendapatkan tingkat kekasaran yang optimum untuk penggunaannya pada tulang berkepadatan rendah. Purwarupa akan diuji dengan uji torsi insersi dan uji pull-out test. Purwarupa 1 menunjukkan performa terbaik dengan nilai kekasaran permukaan sebesar 1,0636 μm, serta nilai insertion torque value dan pull-out load sebesar 22,4415 Ncm dan 317,068 N.

Tooth loss has become a common health issue in Indonesia, with approximately 19% of cases resulting from extraction or natural loss. Dental implant are widely used as an alternative due to their proven long-term effectiveness. The success of dental implant placement is evaluated based on its stability, which can be categorized as primary stability and secondary stability. Both types of stability are interrelated with one another. Concerns about dental implant placement are often encountered when dealing with patients with low bone density. Poor quality and low-density bone in the implant insertion site might result in a higher risk of implant failure. To improve implant stability, various modifications are made to the design and surface of the implant body, such as adding self-tapping features and increasing the surface roughness of the implant body. Fabrication is done to produce dental implant prototypes with variations in in angulation and length of the cutting flute, as a part of the self-tapping feature. These prototypes will undergo surface treatment to achieve an optimal level of surface roughness for use in low bone density. Each prototypes are then tested using insertion torque test and pull-out tests. Prototype 1 showed the best performance with a surface roughness value of 1,0636 μm, as well as an insertion torque value of 22,4415 Ncm and a pull-out load of 317,068 N."

"Penggunaan prosthesis Modular menjadi salah satu solusi terbaik untuk mengobati kanker tulang meskipun mengalami amputasi. Studi ini mengembangkan modular femur MegaProsthesis Distal baru dengan memberikan beberapa modifikasi pada geometri dan juga beberapa fitur. Oleh karena itu, model baru ini dirancang dan disimulasikan dengan menganalisis analisis stres. Desain terdiri dari 4 segmen: segmen distal femur, segmen fiksator, segmen konektor, dan segmen porksimal tibia. Desain terpilih nantinya akan dibuat prototipe menggunakan mesin CNC. Untuk proses pengujian prototipe menggunakan konsep simulasi dari ISO 10328 dan ASTM F1800. Masing masing konsep tersebut mewakili skema uji biomekanik untuk sistem modular implan megaprosthesis distal femur. Terdapat 4 mode uji dari ISO 10328 dan 1 mode uji dari ASTM F1800. Berdasarkan hasil simulasi desain dinyatakan aman dan dapat dimanufaktur untuk nantinya di uji menggunakan skema uji biomekanik yang telah disimulasikan.

The use of a Modular prosthesis is one of the best solutions to treat bone cancer despite an amputation. This study developed a new modular MegaProsthesis Distal femur by providing some modifications to the geometry as well as some features. Therefore, this new model was designed and simulated by analyzing stress analysis. The design consists of 4 segments: the distal femur segment, fixator segment, connector segment, and proximal tibia segment. The selected design will be prototyped using a CNC machine. For the prototype testing process using the simulation concept of ISO 10328 and ASTM F1800. Each of these concepts represents a biomechanical test scheme for the distal femoral megaprosthesis implant modular system. There are 4 test modes from ISO 10328 and 1 test mode from ASTM F1800. Based on the simulation results, the design is declared safe and can be manufactured for later testing using a simulated biomechanics test scheme.

"Topics covered in Long acting Injections and Implants include the historical development of the field, drugs, diseases and clinical applications for long acting injections and implants, anatomy and physiology for these systems, specific injectable technologies (including lipophilic solutions, aqueous suspensions, microspheres, liposomes, in situ forming depots and self-assembling lipid formulations), specific implantable technologies (including osmotic implants, drug eluting stents and microfabricated systems), peptide, protein and vaccine delivery, sterilization, drug release testing and regulatory aspects of long acting injections and implants."

""Specialty Imaging: Dental Implants is a unique textbook written by a team of experts representing every specialty that deals with implant dentistry, but led by an oral and maxillofacial radiologist. This collaborative effort has produced a truly comprehensive reference for anyone involved with imaging for dental implant purposes, including oral and maxillofacial radiologists, oral surgeons, periodontists, technicians, and general dentists. Specialty Imaging: Dental Implants is organized in such a way that it guides the reader from the basics to the post-procedure management of implants. The main topics include: anatomy and nomenclature of dental implants as well as biological and biomechanical considerations; imaging toolbox options, with the utilization of these options for planned implant site evaluation; discussion of common pathology that may be encountered in the analysis of radiographic data with applicable implant correlations; available alveolar process augmentation options based on radiographic imaging data; imaging protocols for post-surgical implant procedure and the radiographic appearances of success; and lastly, the radiographic appearance of complications associated with dental implant treatment. Lead by a board-certified oral and maxillofacial radiologist, Dania Tamimi, BDS, DMSc, and meticulously constructed by her and her multi-specialized team of authors, this reference encourages more inclusion of and collaboration with oral and maxillofacial radiologists for implant planning cases, and educates clinicians on how to use imaging tools efficiently and effectively to get the most out of their radiographic imaging data, resulting in an overall better treatment outcomes for the patient. As with all Amirsys references, all of the information is distilled into succinct, bulleted text with thousands of images and illustrations. Coupled with a companion eBook, this volume will surely become the standard reference textbook for all involved in implant dentistry."--Provided by publisher."

"Commercialisation and growing potential of human ICT implants have generated debate over the ethical, legal and social aspects of the technology, its products and application. Despite stakeholders calling for greater policy and legal certainty within this area, gaps have already begun to emerge between the commercial reality of human ICT implants and the current legal frameworks designed to regulate these products. This book focuses on the latest technological developments and on the legal, social and ethical implications of the use and further application of these technologies."
