The loss of tissues due to trauma, disease or congenital anomalies is a health care issue. Therefore, the development of materials that could be implanted or incorporated into tissues to regain function is of utmost importance. The global market for biomaterials was valued at US $ 66.2 billion in 2015 and is likely to expand to 14% by 2020 (Nagrath et al. 2018). A large part of this market is centralized on mineralized tissues such as orthopedic and craniofacial/dental implants. In dentistry, tooth loss is not seen as an aesthetic or psychological problem; this is definitively a problem with serious physiological consequences. Tooth loss should be considered as an imbalance in the masticatory system. Edentulism can lead directly to impairment, functional limitation, gum damage and alveolar bone resorption (Polzer et al. 2010). For many years, autologous implants were considered the gold standard However, this requires a more significant discomfort for the patient. Here we try to describe the recent advances in dental tissue engineering which will likely produce alternatives to autogenous bone grafts that may well exceed existing clinical outcomes and replace traditional indications for its use (Misch 2010).
The Elderly Dental Patient
Published in Eli Ilana, Oral Psychophysiology, 2020
In 1982, Ettinger and Beck22 attempted to define the social and cultural differences between the “old elderly” (at the time of the study being 75 years and older), and the “new elderly” (then, between 60 and 64 years old). The old elderly grew up during the early part of the century, when dentistry was still perceived as a luxury. The “focal infection” theory, popular at the time, resulted in a high rate of extractions. Local anesthesia was not yet well developed, a fact which often led to unavoided pain and stress. Negative attitudes toward teeth and dentistry were popular and led to avoidance of treatment and early edentulism.
Major preprosthetic surgery, incorporating implants
Published in John Dudley Langdon, Mohan Francis Patel, Robert Andrew Ord, Peter Brennan, Operative Oral and Maxillofacial Surgery, 2017
This technique is indicated for partially or totally edentulous patients, who in addition to their edentulism exhibit two complicating factors: (1) horizontal and/or vertical maxillary deficiency with associated facial deformity and skeletal malocclusion and (2) inadequate bone quality and/or quantity to support endosseous implants in the edentulous area eventually requiring bone-anchored dental prosthesis. These patients are generally younger individuals, who have high functional and aesthetic expectations. They also frequently exhibit high functional disability in mastication, speech, deglutition and nasopharyngeal airflow (Figure 13.3).
Quantitative parameters of digital occlusal analysis in dental implant supported restorative reconstruction recent 5 years: a systematic review

Dental implant-supported restorations are extensively used for the oral reconstruction of partial and complete edentulism after evolving from experimental treatment to highly predictable alternative options of missing teeth in the past 50 years [1–3]. Two primary goals of implant treatment are successful treatment results from the rehabilitation of normal oral physiological functions such as chewing, pronunciation, and aesthetics with high predictability and good long-term stability, in addition, it is crucial to reduce the occurrence of complications during healing and subsequent periods [2,4]. Various methods to evaluate the oral health-related outcomes include chewing efficiency, maximum bite force, patient satisfaction, and patient nutritional status [5–8]. Each method has its advantages, but some indicators are subjective and lack comparability among the outcomes due to different observational contents.

Edentulism is a handicap that has an adverse psychosocial effect on patients (Alzoubi et al. 2017). While improved oral-health maintenance may have led to a reduction in edentulism rates over the past 20 years, edentulism is also affected by demographic trends, namely the increasing number of individuals over age 65 among the general population (Marcus et al. 1996; Turkyilmaz et al. 2010). A complete denture has been the standard treatment for edentulism for more than 100 years. Today, however, treatment of edentulism with conventional complete dentures is no longer the first option offered to patients. Dental implants to retain or support removable and fixed prosthesis emerges as a new treatment approach in daily clinical routine (Mumcu et al. 2020). Despite the need for dental implant support in such cases, the reduction in bone volume and maxillary sinus pneumatization following the extraction of posterior teeth make dental implant insertion a challenge (Galindo and Butura 2012). For the patients with insufficient bone for the insertion of dental implants in the posterior maxillary regions, advanced surgical techniques such as sinus floor augmentation and bone grafting techniques may be applied which are invasive options that entail the risk of post-surgery complications, prolong overall treatment time, and increase treatment costs and may not be accepted by the patients (Clavero and Lundgren 2003; Del Fabbro et al. 2012).
Dietary Oily Fish Intake and Frailty. A Population-Based Study in Frequent Fish Consumers Living in Rural Coastal Ecuador (the Atahualpa Project)

Demographics and cardiovascular risk factors were assessed through interviews and procedures previously described for the Atahualpa Project.22,26 In brief, smoking status and physical activity were based on self-report. The body mass index was calculated after obtaining the person’s height and weight. Fasting glucose and total cholesterol levels were measured after obtaining a capillary blood sample, using Accu-chek® Active and Accutrend® Plus devices (Roche Diagnostics, Mannheim, Germany), respectively. Blood pressure was measured with the use of a manual sphygmomanometer (Welch Allyn Tycos© 7670-01, Skaneateles, NY). Diet, which is one of the health metrics investigated in participants, was not included in the models because of collinearity. A rural dentist performed a mouth examination to count the number of remaining teeth, and those with less than 10 teeth were considered to have severe edentulism.27
