Radiosurgical Techniques
Published in Jeffrey A Sherman, Oral Radiosurgery, 2020
A 46-year-old female reported to the office with decayed and missing teeth. After clinical, periodontal and radiographic examination, it was decided to construct a permanent maxillary fixed bridge to restore or replace any decayed or missing teeth.

Patients with an edentulous maxilla are rehabilitated, in large part, by a well-known technique called All-On-4®. This is a minimally invasive procedure consisting of replacing all maxillary teeth using only 4 dental implants, which will support a fixed bridge that is screwed to the implants. Maló and colleagues advocated the following distribution: two anterior implants positioned in the lateral incisor regions, one on each side, and two posterior implants in the premolar regions, one on each side, positioned at 30° of inclination in relation to the occlusal plane tangential to the anterior wall of the maxillary sinus (Figure 1(a)) (Malo, Rangert, & Nobre, 2005) (Maló, De Araújo Nobre, Lopes, Francischone, & Rigolizzo, 2012). This configuration allows the rehabilitation of an arch with 12 dental elements, with a distal cantilever in the molar topographies (Dos Santos, Meloto, Bacchi, & Correr-Sobrinho, 2017).

Nicotine gum should be chewed slowly until a peppery or mint taste emerges and then parked between the cheek and the mucosa. It should be alternatively chewed and parked for 30 minutes until the taste disappears. Patients can chew up to 24 pieces of gum per day. Acid drinks, coffee, wine and fruit juices lower the pH in the mouth, theoretically reducing nicotine absorption. The gum can stick to bridges, fillings, dentures and crowns. Nicotine lozenges provide a higher nicotine dose than gum.
Modified Bridge Drawings With a SUD Population in a Residential Setting
Published in Art Therapy, 2022
Bridges are the oldest means of engineering ever conceived by humans (Gies, 1963; Watson, 2006). They have become a fundamental part of our everyday commutes, yet we take for granted their contributions to our daily lives. The bridge is a structure that provides passage over obstacles such as valleys, rough terrain, or bodies of water by spanning those obstacles with natural or manmade materials (Ross, 2018). Its mythic and metaphoric significance has permeated virtually all cultures. The bridge can be associated with transition from life to death or from the secular to the divine, as well as transition from one plane or state of consciousness to another (De Mare, 1954; Fontana, 1994; Jung, 1964). It can be a nexus or relationship joining two separate individuals or entities (Chetwynd, 1982; Cooper, 1978; Fontana, 1994; Jung, 1964).

The diagnosis of periodontitis is based on a standardized periodontal examination protocol, referring to the community periodontal demand Index (CPITN) standard of Muthukumar and Suresh (2009): Periodontal health was examined under adequate natural light by 3 trained oral practicing doctors (reliability test Kappa = 0.97) using the oral CPI probe. All subjects were assigned 10 sites according to the community periodontal index. The adjacent tooth was selected for examination if the index teeth presented sugingival calculus or poor restoration of the crown of the tooth, or the crown was constructed by hammer, or the tooth was used as a bridge abutment. The CAL of all sites was summed to calculate the average attachment loss (AAL): AAL≤ 3 mm were defined as mild CP, 3< AAL<4 mm as moderate CP, AAL≥ 5 mm as severe CP.

Implant surgeries are performed mechanically. Based on imagination, dentists scan the patient’s jaw and proceed with drilling. Thus, this technique might not be accurate, whereas 3D printing technology is a logical method that locates the best position to drill. With accuracy, it creates the entire denture set that would be able to fit in the mouth. The demand for dental crowns, implants, and bridges is growing high. For customized shape, different 3D printing technologies are used mainly binding jet technology. Several process parameters like binder amount, powder spreading speed, and drying powder level are crucial to getting a customized shape. This technique is also useful to create dentures using metallic powder. Teeth manufacturing with FDM techniques showed accuracy [23]. Processes like SLA, SLS, SLM, and EBM are extremely useful to build a plaster model for the patient’s mouth or replace teeth with less time. Globally, Ti-implants and their bioactive application were explored by using different 3D printing processes. Screw vent implants with porous structures are unique ones.
