Snoring / Obstructive Sleep Apnea


Your body is being deprived of the rest it needs to function properly during the day when you are constantly awoken throughout the night. Obstructive Sleep Apnea (OSA) symptoms include, Snoring, Excessive daytime sleepiness, Night time choking, insomnia, morning headaches, difficulty concentrating, memory loss, etc …

Symptoms that your bed partner is likely aware of frequent episodes of obstructed breathing during sleep, snoring, bruxism (tooth grinding).

Long term consequences include risk of hypertension, stroke, and cardiovascular
Disease, diabetes, irritability, learning and memory problems, mental and emotional health issues and sexual dysfunction

Treatment Option by Dentist - Moses Appliance
In addition to lifestyle changes such as good sleep hygiene, exercise, and weight loss, there are three primary ways to treat snoring and OSA:

This appliance therapy is tailor made by your dentist and works by moving your lower jaw and tongue forward, thereby creating more space for you to properly breathe during the night. This reduces or eliminates snoring.

The MosesR Oral Appliances are indicated for
• Patients with primary snoring or mild to moderate OSA who are intolerant of or refuse treatment with CPAP.
• Do not respond to behavioral measures such as weight loss or sleep position change.
• Patients with moderate to severe OSA who are intolerant of or refuse treatment with CPAP.
• Patients who are not candidates for surgery.

人工植牙


哪些人適合進行人工植牙?
若牙齒移位及鬆脫,例如牙周病,可進行人工植牙療程,並不受年齡限制,惟青少年因骨骼尚未完全發育,可能未必合適。此外,患有嚴重糖尿病骨質疏鬆腎病愛滋病口腔內骨骼不足,以及精神上對植牙過於恐懼的人士,也不適合進行人工植牙。事實上,牙科醫生會先為患者做臨床檢查,並以數碼化儀器檢查後,預測植牙的位置及植體大小等,才診斷是否適合進行人工植牙手術。


如何進行人工植牙?
注射麻醉藥後,先脫掉上顎或下顎牙齒,把牙床消毒,然後鑲嵌由鈦金屬或鈦合金製造的人工植體,完成後即可印牙模,度身訂做臨時牙橋,數小時後,臨時牙橋製成,牙科醫生會用螺絲將牙橋鑲嵌於人工植體上。術後約3個月,當植體與牙床骨結合,以及植體附近的牙肉收縮穩定,牙科醫生會為患者再印製牙模及安裝,植牙手術正式完成。

人工植體由鈦金屬製成,具有生物相容性,可非常穩固支撐假牙。而植牙使用的牙橋及假牙冠,由陶瓷及樹脂等不同材料製成,耐用堅固,醫生會按照患者情況而使用合適材料。一般情況下,單顆植牙的手術時間約需半小時,而進行上頜或下頜半口植牙手術,約需1天時間。


人工植牙與傳統牙橋有何分別:
傳統牙橋的穩定性及咬合能力較差,影響咀嚼感覺,並且需要每日脫下清洗。佩戴時需要將鄰牙磨小,影響鄰牙的健康,更會較易造成齒槽骨的吸收。相反,人工植牙只需四至六顆人工植體,可支撐十至十二隻假牙,並固定於口腔內,不需取出,十分穩固,省時方便。而且,進行人工植牙不會損害其他健康牙齒。陶瓷的牙冠亦很耐用,咀嚼感覺仿如真牙。


人工植牙有何優點?

  • 不需要鄰牙支撐,不用磨小健康的牙齒。
  • 不用每日除下清洗。
  • 鈦金屬的人工植體,耐用穩固,單顆可支撐十至十二隻假牙。
  • 人工植牙穩定性高,不會影響咀嚼感覺。
  • 人工植牙的成功率高,下顎為95%,上顎為90%。



什麼是全頜植牙?
All –On- Four全頜植牙手術,即將全頜牙橋固定在上下顎各四至六顆的鈦金屬人工植體上。牙科醫生會為患者做臨床檢查,並以數碼化軟件,預測植牙的位置及植體大小,若適合進行全頜植牙,會先脫掉上顎或下顎牙齒,把牙床徹底消毒,然後分別在上下顎植入四至六顆鈦金屬的人工植體。鑲入人工植體後,可印製牙模製造臨時全頜牙橋,接著牙科醫生會用螺絲把牙橋鑲嵌在植體上。一般情況下,在進行上或下顎植牙手術後,翌日可進行另一邊手術。

約在3個月後,若人工植體附近的牙肉癒合,植體與牙床骨亦已經結合,便可以鑲嵌新的全頜牙橋。術後患者需每年進行檢查及維修。 此手術以局部麻醉進行,如有需要,可進行全身麻醉。
