The present pilot study could not confirm an immediate rise in bite force after implant rehabilitation. Instead, improvements were mainly noted up to 3 months after surgery and rehabilitation. Furthermore, it became evident that despite gradually improved bite force in all patients, masticatory efficiency and food hardness perception did not necessarily follow the same trend. The present findings...
Occlusal contact was significantly increased 3 months after implant rehabilitation when compared to stage one (prior to implant rehabilitation). We assumed the reason was that some participant’s occlusion was worn down because the material of provisional restoration was resin.

Hardness perception became better after implant rehabilitation, with a reduction of the error rate by 16% (Fig. 3). While five out of eight participants performed better in this test after rehabilitation, the results in the others were less clear. More detailed analysis showed that, despite wearing dentures, four participants were 100% successful in recognition of hardness before implant surgery,...
Two participants were unavailable to attend the testing at 1–2 weeks after the provisional restoration had been inserted, which resulted in missing data.
Overall descriptive analyses yielded the following observations for the four tests.

To assess the hardness differences, the examiner placed each test specimen on the tongue with chopsticks, and then the participants chewed on all sides and swallowed.

To assess the masticatory efficiency, we used glucose extraction in the filtrate obtained after chewing the specimen. After rinsing the mouth with tap water, a gum-like specimen mixed with 5% glucose with a height of 10 mm (Glucosensor Gummy, GC, Tokyo, Japan) was placed on patient’s tongue with chopsticks. Patients were requested to chew on the cube for 20 s, after which, they expectorated al...
Six females and 2 males (average age 66.4 years, range 52–85 years) with upper (n = 7) or lower (n = 1) complete dentures participated in this study. Inclusion criteria were (1) an opposite jaw that included natural dentition at least to the second premolar on both sides, (2) a need for fixed rehabilitation, (3) no medical contraindication to the placement of implants, (4) no need for ...
The purpose of this pilot investigation was to use testing methodologies involving four aspects of masticatory adaptation after rehabilitation with an immediately loaded implant-supported prosthesis and to observe the recovery of each aspect respectively. Our hypothesis is that bite force may recover quickly, but other aspects will require monitoring and recording in order to form an overall judgm...
In addition, it also remains to be demonstrated how a potential compensatory mechanism might work, with one of the options being osseoperception [2, 18–23]. In this context, it is also important to consider the adaptation time needed after oral rehabilitation. Some studies have performed longitudinal evaluations of masticatory function for more than 3 years [24, 25]. However, there are limited ...
Tooth loss represents a major oral disability comparable to an amputation, with severe impairment of oral functions [1]. While denture wearers can rely on mucosal sensors, anchoring prosthetic teeth to the bone via osseointegrated implants has been assumed to create a (partial) sensory substitution for missing periodontal ligament receptors from stimuli transmitted via the bone [2]. The restoratio...
When teeth are extracted, sensory function is decreased by a loss of periodontal ligament receptions. When replacing teeth by oral implants, one hopes to restore the sensory feedback pathway as such to allow for physiological implant integration and optimized oral function with implant-supported prostheses. What remains to be investigated is how to adapt to different oral rehabilitations.

Figure 37. Alveolar atrophy
Following multiple- or single-tooth extraction and the subsequent loss of masticatory function, the alveolar ridge will present a series of adaptive alterations known as alveolar atrophy. The alveolar atrophy is characterized by a reduction in the dimensions of the alveolar ridge that is a combination of hard and soft tissue changes.
Figure 7. Parts of lveolar process
The alveolar process, as previously mentioned, is composed of two parts, the alveolar bone proper and the supporting bone. The alveolar bone proper is the bone that lines the socket of a tooth. The function of the alveolar bone proper, together with the root cementum and the periodontal ligament, is to form the attachment apparatus of the tooth.
Figure 6. Tooth-dependent structure
The alveolar process contains the roots of the teeth and developing tooth buds of unerupted teeth. It is a tooth-dependent part of the jaws, since it forms in response to the development and eruption of the teeth. Its final volume and shape are determined by the form of the teeth, their axis of eruption, and their eventual inclination.
