🛑🛑 نقاط مهمه
(1)
*Patient with bad oral hygiene need " full mouth rehabilitation " .
* Diagnosis & evaluation of TMJ must be " before " construction of bridge .
* Treatment of TMJ problems ?
" Depend on the cause "
-If the cause is previous bridge ... the treatment is before .
_ If the cause is missing teeth ... the treatment is after .
*What is the objective can be seen only by study cast ?
_Occlusion from lingual aspect .
*Crown root ratio can be seen only by radiograph .
* All cases in crown & bridge need X-ray
(2)
* Main advantage of implant over bridge is " preservation of the bone " .
* Ideal bridge ----> 2 retainers from each side and 1 Pontic .
* Pontic transmit the force of mastication to the abutment through connector .
* It's advisable to use "GIF" glass inomer filling in abutment after removal of caries .
* If Crown root Ratio is less than 1:1 , tooth is not used as an abutment.
* Ante's law :
Sum of Surface area of abutment teeth ÷ Surface area of missing tooth = 1 or more .
( if it's less than 1 " poor prognosis " ---> we may use secondary abutment).
* Tilted abutment can be prepared with adjusting long axis and covered with crown , then retainer is placed over this crown ( crown over crown) or TELESCOPE CROWN.
(3)
* Types of bridge according to position:
_ Anterior or posterior.
_ Upper or lower
* Types of bridge according to material :
_ Full metal
_ PFM
_Full ceramic
* Types of bridge according to construction:
_ Temporary .
_ Long term professional restoration.
_ permanent.
* Indication of fixed_fixed bridge:
_ Heavy occlusion.
_ mobile abutment .
* Indication of fixed _ movable bridge:
_Tilted abutment .
_SOUND Pier abutment .
*Fixed _ movable bridge is contraindicated in case of mobile abutment.
* Fixed _ movable bridge is stress breaker because of slight movement of CONNECTOR durin function.
* Removable Bridge :
Used when most teeth are destructive.
(4)
*Most important factors in resin_bonded bridge :
1) selection of the patient ---> good diagnosis and treatment plan .
2) Cementation " bond agent system " .
* Rochette bridge :
_Macromechanical retention .
_Perforated .
_Rapid loss of retention .
* Maryland bridge :
_ micromechanical retention .
* Indication of resin bonded bridge:
_ when there is no contraindication ----> " the first choice after implant "
* If the abutment is covered with porcelain crown , the cementation and retention is better than enamel.

• اذا معانا فقد في ال4incisors في الlower مافي مشكلة، مادام ان الcanine موجود، نستخدمه كabutement لانه في الlower incisors تكون:-
forces of mastication parallel with the long axis of teeth.
so we can use the 2 canines as abutement for missing 4incisors
but in upper incisors there is torqing forces, and tipping forces.
so replacing upper 4incisors may need the 2canines, and 2 premolars as an abutements.
» missing upper canine:-
- in normal occlusion:-
abutement»»
central, lateral, and first premolar
- less than normal occlusion:-
abutement»»
lateral incisor, and first premolar
- in heavy occlusion:-
abutement»»
central, lateral, 2 premolars
so in heavy occlusion implant may be considered in replacement of canine.
»importance of canine:-
• situated in the corner of the mouth
• طبعا أثناء الحركة الأمامية للفك السفلي
اللي يقود هذه الحركة او يوجهها هي الlingual surfaces of upper anterior teeth
وال contact يكون عندها بس اثناء الحركة
• بينما في الحركة الجانبية، المنطقة الوحيدة اللي يحصل فيها. contact هي الlingual surface of upper canine لذلك كل القوة مسلطة عليه،
• بالإظافة الى ان الforce of mastication
ماتكون موازية للlong axis of upper canine
هذه كلها لازم تكون في عين الاعتبارر لما نعوض الupper canine.
• canine guidence:-
the whole force is concentrated on canine during lateral movement.
• group guidence:-
the force on canine is reduced when premolar receive part of this force.
• متى نستخدم الlateral incisors. كabutement للcentral incisors؟
» في حالة الopen bite فقط.
» او في حال كان الآطباق»»»
less than normal
يعني اذا الlower فيه؛-
bridge,removable partial denture, complete denture.
- بس اذا كان الاطباق normal، بهذه الحالة ضروري نستخدم الlateral incisors&canine , كabutement
- alternative solution is to use 3/4 crown on canine instead of full preparation.
- there are different forces which keeps the tooth in its position.
- the sum of this forces is zero.
- this forces are:-
• proximal contact.
• occlusal contact.
• tongue.
• check
• lip
لو قل مقدار واحدة من هذه الforces يبدأ السن يتحرك.
- some of this movements:-
• tilting
• super erruption
»لذلك في حال فقدان الlower 6 مثلا...
لازم نشوف السن المقابل قبل مانعوض
فإذا كان الsupererruptiom فيه نص مللي،
نحضر السن هذا ونعملsmoothening and polishing
بحيث انه التحضير حقنا ماتجاوزش طبقة الenamel
بس اذا كان الovererruption في السن المقابل 1-1.5ml، نحضر السن ونعمل له crowning لأنه التحضير قد وصل للدنتين.
• اذا تبقت thin layer of enamel، ضروري نكمل تحضير... لحد 2ml ونعمل crowning.
• اذا الover eruption اكثر من 1.5ml نعمل reduction for opposing tooth& endo
& crown
• اذا كان الover eruption اكثر من كذا، وشفنا السن مثلآ قد انكشف الroot تبعه بنسبة كبيرة»» نخلع الopposing tooth ونعمل:-
• upper and lower implant.
or
• upper and lower bridge
»why we must do this?
• لأنه إذا عملنا الbridge وأهملنا مشكلة الover erruption بيحصل اختلال في الاطباق premature contact او high spot
بحيث انه المريض لما يأكل او يحرك الفك، يكون في abnormal contact تعيق الحركة ، فيضطر المريض يغير مسار الفك اثناء الحركة علشان يتلافى الcontact، وبالتالي نشأت مشكلة في الTMG
CREATED PROBLEM
Tilted tooth
• the ideal solution is orthodontic uprighting of tilted tooth, and then implant or bridge to restore the missing.
• mesial half crown... but need good oral hygien patient.
• non rigid connector:-
نعمل للسن non rigid connector ) key and key way) الغرض منه انه نعمل parallism للpath of insertion من دون مانحضر كمية كبيرة من الtilted tooth.
نعمل crown للtilted tooth بحيث يكون الpath of insertion حقه موازي للسن نفسه
، لكن نعمل جزء الnon rigid connector الkey way موازي للpath of insertion of the other abutement
• telescope crown ( crown over crown)
نحضر الtilted tooth ونعمل له crown ونثبته عليه... يصبح جزء من السن، بعدين ناخذ طبعة ونصبها ويتم تصنيع الbridge النهائي على الcast هذا
يكون معانا 2crowns الاول اللي على السن مباشرة copy, والثاني اللي تبع الbridge
والغرض النهائي واحد لكل الطرق السابقة ..... وهو انه نأمن path of insertion للbridge من دون مانحضر كمية كبيرة من ال tilted tooth.

PAIR ABUTEMENT
الpair ABUTEMENT واقعة بين two edentiolus spaces
وبيكون معانا abutement tooth نهاية كل edentiolus space ، والpair abutement تكون تحت تاثير قوة الشد الناتجة من الtwo abutement
فإذا كانت:-
• sound pier abutement with no periodontal problems
نستخدم معاها ال fixed movable bridge, وهذا يحتوي على rigid connector في جهة وnon rigid connector في جهة اخرى لكسر ال stress اللي تتعرض له ال pier abutement. لانه ال non rigid connector
يسمح بحركة بسيطة على عكس الrigid connector يكون ثابت.
لكن اذا كانت:-
• pier abutement suffer from periodontal problems and undergo some mobility
بهذه الحالة نستخدم ال fixed- fixed bridge
لأنه السن أصلآ فيها periodontal problem
وفيها حركة، فالحركة الناشئة من الnon rigid connector بتزيد المشكلة.
لذلك نستخدم الfixed- fixed bridge
لأنه يعمل. splinting او تدعيم للأسنان، وبيخفف مشكلة الperiodontal.
