    Notes: In eighteen subjects assigned for immediate complete upper and lower dentures, roentgen cephalometric recordings were made before extraction of the residual anterior dentition and 3 weeks, 3 months, 6 months and 1 year after denture insertion. The cephalometric analysis was based on electronic measurements of linear and angular morphological variables and computer head plots generated from 177 reference points (Walker, 1967), derived for each subject for each of the five observation stages.The reduction of the alveolar ridges was most rapid during the first 3 months of denture wear and particularly during the post-extraction period of 3 weeks. The reduction in anterior height of the lower ridge was on average twice as great as that of the upper ridge. The ridge resorption and the accompanying settling of the dentures on the basal seats, measured from lead shots inserted in the dentures, brought about an upward rotation of the mandible with a resulting decrease in occlusal vertical dimension and reduction in overjet of the dentures. In accordance with the amount of ridge reduction, these changes showed great individual variation.

    The effect of acrylic bite plane splints and their vertical dimension on jaw muscle silent period in healthy young adults (1985)

    Notes: A significant question relative to treatment and disappearance of symptoms is raising the bite in combination with a maxillary bite plane splint in patients with TMJ muscle dysfunction. The objective of this research was to investigate the effect, if any, occlusal bite plane splints have on the latency and duration of the menton tap silent period and particularly whether the degree to which the bite is raised is of significance. Recordings were made in healthy young adults from both anterior temporal and masseteric muscles while subjects were clenching at their 70% maximum clenching effort. Placement of a splint significantly (P〉0·05) prolonged the silent period duration (SPD). However, mean SPD values taken at two different vertical raised bites did not differ significantly (P〉0·05). The anterior temporal muscle SPD was less sensitive to a smaller change of vertical dimension than the masseteric SPD. Silent period latencies remained unchanged in all experimental conditions.

    The refractory period of the masseteric cutaneous silent period (1985)

    Notes: Silent periods were elicited in the electromyographic activity of the masseter and temporalis muscles from six normal subjects, by electrical stimulation of the skin over the contralateral masseter during clenching. Pairs of suprathreshold square pulses with varied time intervals were delivered using surface electrodes. It was found that the silent periods, which were mostly of the long latency (about 53 ms) type, had a refractory period, during which a new silent period could be evoked only by increasing the strength of the second stimulus. This refractory period could last for up to 1.5 s. During the first 200 ms after the first stimulus a second silent period was almost impossible to evoke with the moderately painful stimuli used in the present experiments. It is suggested that the refractory period should be considered as significant for the methodology when recording the silent period duration. It is also suggested that the long latency silent period should be recorded as a separate parameter and differentiated from the short latency (10–12 ms) silent period. This may be of special importance to recognize when a short latency silent period and a long latency silent period merge.

    Paradigmatic shifts in occlusion and temporomandibular disorders (2001)

    Notes: There are several terms that identify proposed paradigms for the way things ought to be carried out in the health sciences: evidence-based, cause-and-effect, diagnostic gold-standard, patient-centred-outcomes, risk assessment, cost/benefit/risk, and efficacious/effective. Collectively these paradigms exhibit varying degrees of interdependence, and have the potential for changing the way dentistry is practiced. A paradigm can be thought of as a standard by which research and health science ought to be conducted and evaluated. In this sense scientists and clinicians try to figure out how to account for various observations and phenomena dictated by paradigms or models of health care; however, it may become necessary to shift to new paradigms that are more consistent with scientific and clinically reality. Some of the potential effects of these shifting paradigms on the practice and teaching of occlusion and temporomandibular disorders are considered.
